The official US presence in Algeria is expanding following over a decade of limited staffing, reflecting the general improvement in the security environment. During the past three years, the US embassy has moved toward more normal operations and now provides most embassy services to the American and Algerian communities.

After the 1973 Arab-Israeli War, Egyptian foreign policy began to shift as a result of the change in Egypt's leadership from President Gamal Abdel-Nasser to Anwar Sadat and the emerging peace process between Egypt and Israel. Sadat realized that reaching a settlement of the Arab-Israeli conflict is a precondition for Egyptian development. To achieve this goal, Sadat ventured to enhance Egypt–United States relations to foster a peace process with Israel.

In 2011, the United States cut diplomatic relations with the Gaddafi regime. The United States recognized the National Transitional Council as the legitimate government of Libya on July 15, 2011.^[109]

Morocco was the first sovereign nation to recognize the United States in 1777. American-Moroccan relations were formalized in a 1786 treaty, which is still in force and is the oldest unbroken bilateral treaty in American history.

Relations were tense during the Angolan Civil War when the US government backed UNITA rebels, but have warmed since the Angolan government renounced Marxism in 1992.

The two nations have had an excellent history of relations in the years since Benin embraced democracy. The US government continues to assist Benin with the improvement of living standards that are key to the ultimate success of Benin's experiment with democratic government and economic liberalization, and are consistent with US values and national interest in reducing poverty and promoting growth. The bulk of the US effort in support of consolidating democracy in Benin is focused on long-term human resource development through USAID programs.^[115]

Bilateral relations between the United States and Uganda have been good since Yoweri Museveni assumed power, and the United States has welcomed his efforts to end human rights abuses and to pursue economic reform. Uganda is a strong supporter of the Global War on Terror. The United States is helping Uganda achieve export-led economic growth through the African Growth and Opportunity Act and provides a significant amount of development assistance. At the same time, the United States is concerned about continuing human rights problems and the pace of progress toward the establishment of genuine political pluralism.

The diplomatic relationship between the United States and Zambia can be characterized as warm and cooperative. The United States works closely with the Zambian Government to defeat the HIV/AIDS pandemic that is ravaging Zambia, to promote economic growth and development, and to effect political reform needed to promote responsive and responsible government. The United States is also supporting the government's efforts to root out corruption. Zambia is a beneficiary of the African Growth and Opportunity Act (AGOA). The US government provides a variety of technical assistance and other support that is managed by the Department of State, USAID, Millennium Challenge Corporation (MCC) Threshold Program, Centers for Disease Control and Prevention, Department of the Treasury, Department of Defense, and the Peace Corps. The majority of US assistance is provided through the President's Emergency Plan for AIDS Relief (PEPFAR), in support of the fight against HIV/AIDS.

After Morgan Tsvangirai, Mugabe's rival and leader of the Movement for Democratic Change, became Prime Minister of Zimbabwe under a power-sharing agreement, the Barack Obama administration extended its congratulations to Tsvangirai, but said that the US would wait for evidence of Mugabe's cooperation with the MDC before it would consider lifting its sanctions.^[162] In early March 2009, Obama proclaimed that US sanctions would be protracted provisionally for another year, because Zimbabwe's political crisis is as yet unresolved.^[163]

Turkey participated with the United States during the Korean War of the early 1950s and the Gulf War of 1990.

The United States was the third country to establish formal diplomatic relations with the UAE and has had an ambassador resident in the UAE since 1974. The two countries have enjoyed friendly relations with each other and have developed into friendly government-to-government ties which include security assistance. UAE and US had enjoyed private commercial ties, especially in petroleum. The quality of UAE–US relations increased dramatically as a result of the US-led coalition's campaign to end the Iraqi occupation of Kuwait. UAE ports host more US Navy ships than any port outside the US.

Traditionally, United States – Yemen relations have been tepid, as the lack of strong military-to-military ties, commercial relations, and support of Yemeni President Ali Abdullah Saleh has hindered the development of strong bilateral ties. During the early years of the George W. Bush administration, relations improved under the rubric of the War on Terror, though Yemen's lack of policies toward wanted terrorists has stalled additional US support.^[184]

The US embassy, USAID, and the Peace Corps are located in Ashgabat, Turkmenistan. The United States and Turkmenistan continue to disagree about the country's path toward democratic and economic reform. The United States has publicly advocated industrial privatization, market liberalization, and fiscal reform, as well as legal and regulatory reforms to open up the economy to foreign trade and investment, as the best way to achieve prosperity and true independence and sovereignty.

Relations improved slightly in the latter half of 2007, but the U.S.A. continues to call for Uzbekistan to meet all of its commitments under the March 2002 Declaration of Strategic Partnership between the two countries. The declaration covers not only security and economic relations but political reform, economic reform, and human rights. Uzbekistan has Central Asia's largest population and is vital to US, regional, and international efforts to promote stability and security.

In 2021, the Taliban overthrew the U.S.-backed Islamic Republic of Afghanistan concurrent with the withdrawal of U.S. troops, leading to the relocation of the U.S. Embassy in Kabul to Doha, Qatar.^[190] On November 12, 2021, the U.S. announced that an interests section would open at the Embassy of Qatar in Kabul on December 31, to serve as the protecting power for the U.S. in Afghanistan.^[191] The Islamic Republic's diplomatic missions to the U.S. operated independently for several months before shutting down operations and transferring custody of the properties to the U.S. State Department on March 16, 2022. Afghanistan has no protecting power in the U.S.^{[192][193][194]}

Today the relationship between the two countries is based on what is described by American diplomats as the "three Ds", meaning Democracy, Development and Denial of space for terrorism. The United States is closely working with Bangladesh in combating Islamic extremism and terrorism and is providing hundreds of millions of dollars every year in economic assistance.

While the United States has no formal diplomatic relations with Bhutan, it maintains informal contact through its embassy in New Delhi, India. The US has offered to resettle 60,000 of the 107,000 Bhutanese refugees of Nepalese origin now living in seven UN refugee camps in southeastern Nepal.

The relationships between India in the days of the British Raj and the US were thin.^[198] Swami Vivekananda promoted Yoga and Vedanta in America at the World's Parliament of Religions in Chicago, during the World's Fair in 1893. Mark Twain visited India in 1896^[199] and described it in his travelogue Following the Equator with both revulsion and attraction before concluding that India was the only foreign land he dreamed about or longed to see again.^[200] Regarding India, Americans learned more from English writer Rudyard Kipling.^[201] Mahatma Gandhi had an important influence on the philosophy of non-violence promoted by Martin Luther King Jr. in the 1950s.

At present, India and the US share an extensive and expanding cultural, strategic, military, and economic relationship^{[202][203][204][205][206]} which is in the phase of implementing confidence building measures (CBM) to overcome the legacy of trust deficit – brought about by adversarial US foreign policies^{[207][208][209][210]} and multiple instances of technology denial^{[211][212][213][214][215]} – which have plagued the relationship over several decades.^[216][217] Unrealistic expectations after the conclusion of the 2008 India–United States Civil Nuclear Agreement (which underestimated negative public opinion regarding the long-term viability of nuclear power generation and civil-society endorsement for contractual guarantees on safeguards and liability) has given way to pragmatic realism and refocus on areas of cooperation which enjoy favourable political and electoral consensus.

The United States relationship with Pakistan weakened after the United States troops withdraws Afghanistan in 2021.^[221] Pakistan declined an invitation to the US's 'Summit for Democracy' under the Biden administration.^[222]

The United States and the People's Republic of China have extensive yet complex economic relationships and partnerships. A great amount of trade between the two countries necessitates positive economic relations, although occasional disagreements over tariffs, currency exchange rates, intellectual property theft, and the political status of Taiwan occurs. The United States has criticized China on such human rights issues as the 1989 Tiananmen Square protests, the persecution of Falun Gong, and more recently the mass detaining of Uyghurs, Kazakhs, and other ethnic and religious minorities in Xinjiang, as well the forced sinicization of Mongols and Tibetans. China has criticized the United States on human rights issues in response and accused the latter of "interfering in China's internal affairs". The United States acknowledges the PRC's One-China policy.

The relations deteriorated sharply under Chinese Communist Party general secretary Xi Jinping, with issues such as China's militarization of the South China Sea and Chinese espionage in the United States arising. U.S. president Donald Trump launched a trade war against China, banned U.S. companies from selling equipment to Huawei, increased visa restrictions on Chinese students and scholars, and designated China as a "currency manipulator".^{[225][226][227][228][229]} The more confrontational policy has endured during the Biden administration, which focuses on China's treatment of Hong Kong, the threats against Taiwan, the persecution of Uyghurs in China, and Chinese cyberwarfare. In response, China has adopted "wolf warrior diplomacy" to counter allegations they see as incorrect and damaging to the American-Chinese dialogue.

2018 (Taiwan Travel Act) - high-level working partnership

The United States recognized the Nationalist Government as the legitimate government of all of China throughout the Chinese Civil War. The U.S. continued to recognize the Republic of China until 1979, when it shifted its recognition to the People's Republic of China in accordance with the One China policy, where the U.S. 'acknowledge', or take note of, the Chinese position on Taiwan but not 'recognizing' or accepting it, which allows the U.S. flexibility to pursue unofficial but robust relations with Taipei. The U.S. continued to provide Taiwan with military aid after 1979, and continued informal relations through the American Institute in Taiwan, and Taiwan is considered to be a strong Asian ally and supporter of the United States.^[230] The U.S. Congress passed the Taiwan Travel Act on February 28, 2018, and the bill was subsequently signed into federal law by President Donald Trump, formalizing high-level communications between Washington and Taipei as well as permitting intergovernmental contact at the highest level.^[231]

U.S. foreign policy toward Hong Kong, grounded in a determination to promote Hong Kong's prosperity, autonomy, and way of life, is stated in the U.S.–Hong Kong Policy Act of 1992. It rules that the U.S. would continue to treat Hong Kong apart from the People's Republic of China even after the 1997 transfer of sovereignty marking the end of British rule. The United States maintains substantial economic and political interests in Hong Kong. The United States supports Hong Kong's autonomy by concluding and implementing bilateral agreements; promoting trade and investment; arranging high-level visits; broadening law enforcement cooperation; bolstering educational, academic, and cultural links; and supporting the large community of U.S. citizens and visitors.

In recognition of Macau's high degree of autonomy, the United States continues to treat Macau as a "special area" distinct from the People's Republic of China. Macau's clothes and textiles continued to enter the United States under quotas separated from those of China. Under the terms of a September 2000 bilateral Memorandum of Understanding, Macau and the U.S. government cooperate in enforcing textile quotas and preventing illegal trans-shipment. The United States continued periodic visits by U.S. Customs Textile Production Verification Teams to ensure compliance with Macau bilateral textile commitments.

The relationship began in the 1850s, as the United States was a major factor in forcing Japan to resume contacts with the outer world beyond a very restricted role. In the late 19th century, the Japanese sent many delegations to Europe, and some to the U.S., to discover and copy the latest technology and thereby modernize Japan very rapidly and allow it to build its own empire. There was some friction over control of Hawaii and the Philippines, but Japan stood aside as the U.S. annexed those lands in 1898. Likewise, the U.S. did not object when Japan took control of Korea. The two nations cooperated with the European powers in suppressing the Boxer Rebellion in China in 1900, but the U.S. was increasingly troubled about Japan's denial of the Open Door Policy that would ensure that all nations could do business with China on an equal basis.^[235]

President Theodore Roosevelt admired Japan's strength as it defeated a major European power, Russia. He brokered an end to the war between Russia and Japan in 1905–6. Anti-Japanese sentiment (especially on the West Coast) soured relations in the 1907–24 era. In the 1930s, the U.S. protested vehemently against Japan's seizure of Manchuria (1931), its war against China (1937–45), and its seizure of Indochina (Vietnam) 1940–41. American sympathies were with China and Japan rejected increasingly angry American demands that Japan pull out of China. The two nations fought an all-out war 1941–45; the U.S. won a total victory, with heavy bombing (including two atomic bombs on Hiroshima and Nagasaki) that devastated Japan's 50 largest industrial cities. The U.S. Army under Douglas MacArthur occupied and ruled Japan, 1945–51, with the successful goal of sponsoring a peaceful, prosperous and democratic nation.^[236]

In 1951, the United States and Japan signed Treaty of San Francisco and Security Treaty Between the United States and Japan, subsequently revised as Treaty of Mutual Cooperation and Security between the United States and Japan in 1960, relations since then have been excellent. The United States considers Japan to be one of its closest allies, and it is both a Major Non-NATO ally and NATO contact country. The United States has several military bases in Japan including Yokosuka, which harbors the US 7th Fleet. The JSDF, or Japanese Self Defense Force, cross-train with the U.S. military, often providing auxiliary security and conducting war games.

South Korea–United States relations have been most extensive since 1945, when the United States helped establish capitalism in South Korea and led the UN-sponsored Korean War against North Korea and China (1950–53).^[242] South Korea's rapid economic growth, democratization and modernization greatly reduced its U.S. dependency. Large numbers of U.S. forces remain in South Korea. On September 24, 2018, U.S. president Donald Trump signed a renegotiated trade agreement with South Korean President Moon Jae-in.^[243]

The United States welcomed Brunei Darussalam's full independence from the United Kingdom on January 1, 1984, and opened an embassy in Bandar Seri Begawan on that date. Brunei opened its embassy in Washington, D.C. in March 1984. Brunei's armed forces engage in joint exercises, training programs, and other military cooperation with the US. A memorandum of understanding on defense cooperation was signed on November 29, 1994. The Sultan of Brunei visited Washington in December 2002.

As the largest ASEAN member, Indonesia has played an active and prominent role in developing the organization.^[249] For United States, Indonesia is important for dealing with certain issues; such as terrorism,^[250] democracy, and how United States project its relations with Islamic world, since Indonesia has the world's largest Islamic population, and one that honors and respects religious diversity.^[251] The United States views Indonesia as a potential strategic ally in Southeast Asia.^[252] During his stately visit to Indonesia, US president Barack Obama has held up Indonesia as an example of how a developing nation can embrace democracy and diversity.^[253][254]

Despite increasingly strained relations under the Mahathir Mohamad government, ties have been thawed under Najib Razak's administration. Economic ties are particularly robust, with the United States being Malaysia's largest trading partner and Malaysia is the tenth-largest trading partner of the US. Annual bilateral trade amounts to $50 billion. The United States and Malaysia launched negotiations for a bilateral free trade agreement (FTA) in June 2006.

The United States and Malaysia enjoy strong security cooperation. Malaysia hosts the Southeast Asia Regional Center for Counterterrorism (SEARCCT), where over 2000 officials from various countries have received training. The United States is among the foreign countries that has collaborated with the center in conducting capacity building programmes. The United States and Malaysia share a strong military-to-military relationship with numerous exchanges, training, joint exercises, and visits.

US and European government sanctions against the military government, alongside boycotts and other types direct pressure on corporations by western supporters of the Burmese democracy movement, have resulted in the withdrawal from Burma of most United States and many European companies. However, several Western companies remain due to loopholes in the sanctions.^[258] Asian corporations have generally remained willing to continue investing in Myanmar and to initiate new investments, particularly in natural resource extraction.

Ongoing reforms have improved relations between Burma and the United States. However the Rohingya Crisis has been deteriorating ties.^[259]

The Philippines and the United States have an extremely strong relationship with each other due to their long-standing alliance. The Philippine-USA links stretch back in time. The first Asians in the Americas were the Filipinos.^[261]

The first recorded advent of Filipinos in what is now the United States date to October 1587 around Morro Bay, California,^[262] with the first permanent settlement in Louisiana in 1763,^[263] they were named "Manilamen" and they served in the Battle of New Orleans during the closing stages of the War of 1812, when the British Empire and American Republic once again went to war against each other as Filipinos in Saint Malo supported the American side against the British Empire. One American state, due to it being a former Spanish territory, Texas, was even once called "The New Philippines", so named since the Spanish wanted to replicate the prosperity they achieved in the Philippines, in that territory in the Americas.^[264]

The Spanish government ceded the Philippines to the United States in the 1898 Treaty of Paris that ended the Spanish–American War and led to the Philippine–American War. The Philippines was a United States colony from 1898 to 1946. The United States finally recognized Philippine independence on July 4, 1946, in the Treaty of Manila.^[265] July 4 was observed in the Philippines as Independence Day until August 4, 1964, when, upon the advice of historians and the urging of nationalists, President Diosdado Macapagal signed into law Republic Act No. 4166 designating June 12 as the country's Independence Day.^[266]

The United States and the Philippines have fought together in many conflicts such as World War I, World War II, the Korean War, Vietnam War, Islamic insurgency in the Philippines, Gulf War and the War on Terror.

The Philippines and the United States still maintain close, friendly, diplomatic, political and military relations with more than 100,000 US citizens and nationals living in the Philippines and more than 4 million Filipinos living in the United States. Both countries actively cooperate in the trade, investment and financial sectors. The US is also the largest investor in the Philippine economy with an estimated total worth of $63 billion.

The United States and the Philippines conduct joint military exercises called the Balikatan that take place once a year to boost relations between the two countries. The US military also conducts humanitarian and aid missions in the Philippines. The Philippines is one out of two major US allies in South East Asia.

Since 2003 the US has designated the Philippines as a Major non-NATO ally. However, relations between the United States and the Philippines began to deteriorate in 2016 with Philippines president Rodrigo Duterte wanting to form an alliance with China and Russia and separating the country from all connections and ties with the United States, both economically and socially.

After a 20-year hiatus of severed ties, President Bill Clinton announced the formal normalization of diplomatic relations with Vietnam on July 11, 1995. Subsequent to President Clinton's normalization announcement, in August 1995, both nations upgraded their Liaison Offices opened during January 1995 to embassy status. As diplomatic ties between the nations grew, the United States opened a consulate general in Ho Chi Minh City, and Vietnam opened a consulate in San Francisco. Today, the United States views Vietnam as a potential strategic ally in Southeast Asia.^[252]
