North Kosovo crisis

In 2011, Kosovo Police crossed into the predominantly Serb municipalities of northern Kosovo, without consulting either Serbia or KFOR/EULEX, in an attempt to assert control over administrative border crossings. This action precipitated the North Kosovo crisis, in which the Jarinje administrative checkpoint was burned down and protestors from the Serb community blocked access to the area's roads over a period of several months. Relations between Serb protestors and the international forces were often tense throughout this time. Ristić said that Kosovo Serbs would use peaceful methods of protest such as barricades and roadblocks,^[25] though he added that it would be "impossible to control the situation" if the Priština government or the international deployments introduced the use of force.^[26] On one occasion, he led the Zubin Potok community in a high-profile standoff against North Atlantic Treaty Organization (NATO) forces over access to the checkpoints; during this action, the protestors defied a NATO deadline to remove their roadblocks.^[27][28] Ristić said that his community would only permit KFOR and EULEX forces to cross the barricades "when they will confirm their neutrality ... and withdraw Kosovo customs officials from the two crossings."^[29]

During the crisis, Ristić and other Kosovo Serb leaders met with Serbian president Boris Tadić in a bid to resolve the situation; their talks were unsuccessful.^[30] Ristić announced the removal of the barricades in February 2012 with the underlying issues still unresolved.^[31]

In May 2012, municipal authorities in Zubin Potok and the neighbouring community of Zvečan organized new local elections, as their mandates from the previous cycle were drawing to a close. The broader diplomatic situation had changed since 2008, and these elections were not recognized as legitimate by either Belgrade or Priština.^[32] The DSS won another majority victory in Zubin Potok and Ristić once again continued as mayor.^[33][34] Despite its opposition to the vote, the Serbian government did not overturn the results.

The Belgrade and Priština governments agreed to a system of integrated border management in northern Kosovo later in late 2012. Ristić and other Kosovo Serb leaders met with Tadić's successor Tomislav Nikolić and Serbian prime minister Ivica Dačić prior to the implementation of the new system. After the meeting, Ristić was quoted as saying, "If we receive some sort of guarantee that we will not pay customs at the borders to the sham state of Kosovo, that no one will force us to change our citizenships and personal documents, then we will certainly not create any problems [...] We do not plan to create problems anyhow, apart from exercising our right to pursue the peaceful protests because we cannot allow anyone to force Priština's will upon us."^[35] He later led a further round of protests at the border crossing when these guarantees were not provided, though in December 2012 he acknowledged that there was insufficient popular turnout from the Serb community for the protests to continue.^[36]

Opposition to the 2013 Brussels Agreement

Ristić criticized the absence of Kosovo Serb voices from the negotiations that led to the 2013 Brussels Agreement, which normalized some relations between Serbia and Kosovo while leaving larger questions on the status of the territory unresolved.^[37] He ultimately rejected the agreement and led protests against its implementation.^[38] He was quoted as saying, "It is not an agreement, it is a surrender; they have killed the state in these parts and betrayed Serbs in Kosovo-Metohija."^[39][40]

Serbian political leaders such as Dačić and Aleksandar Vučić later took part in discussions with Ristić and other Kosovo Serb leaders in a bid to win their support for the agreement.^[41] These talks were unsuccessful. Ristić also rejected the Serbian government's call for Kosovo Serbs to participate in the 2013 local elections in Kosovo overseen by the Priština government, describing this course of action as "collective suicide."^[42]

The Serbian government dissolved the municipal assemblies of Zubin Potok and three other Serb municipalities in northern Kosovo in September 2013, bringing Ristić's tenure as mayor to an end.^[43] Despite Ristić's opposition, several members of the Serb community participated in the local elections later in the year.

Parliamentarian

The DSS contested the 2016 parliamentary election in an alliance with Dveri. Ristić received the fourth position on their combined list and was elected when the list won thirteen mandates.^[47] The Serbian Progressive Party (SNS) and its allies won the election, and Ristić served as an opposition member in the term that followed.

Ristić resigned from the DSS in October 2016 against the backdrop of a serious split in the party. He condemned the decision to expel former leader Sanda Rašković Ivić from the party and accused the DSS's new leaders of accommodating themselves to the Progressive Party's rule.^[48] After leaving the DSS, Ristić became a member of the New Serbia–Movement for Serbia's Salvation parliamentary group under Rašković Ivić's leadership. He supported Dveri leader Boško Obradović in the 2017 Serbian presidential election.^[49]

Ristić became an extremely vocal critic of Aleksandar Vučić in his first parliamentary term, accusing the SNS of using a criminal network to intimidate its critics in the Serb communities of northern Kosovo. In a 2017 interview with Vreme, he blamed organized crime for shots that were fired on his family home on election night in 2016 (no-one was injured in the attack). In the same interview, he argued that Serbia should continue to fight for its sovereignty in Kosovo and was quoted as saying, "I do not advocate the division of Kosovo in a geographical sense, but an institutional division should be considered" to ensure Serbs in the territory would have the same right as Albanians to choose their political destiny.^[50]

Ristić became a member of the Otadžbina movement (an organization representing Kosovo Serbs who oppose co-operation with the institutions of the Republic of Kosovo) on its formation in 2017.^[51] In February 2018, he was chosen as the movement's leader.^[52] In this capacity, he has been a vocal opponent of the Serb List's participation in the government of Kosovo.^[53]

Ristić wrote a letter to Russian president Vladimir Putin in 2018 alleging that the Serbian government was planning to sign a comprehensive agreement with the Priština authorities. Among other things, Ristić accused Aleksandar Vučić of co-operating with Priština because of a "promise to the West." The letter included the statement, "The tragic fate of late Serbian Prime Minister Zoran Đinđić [who was assassinated in 2003] is a clear warning to [Vučić] about what happens to those who do not fulfill such a promise." This statement prompted disparate reactions. The Progressive Party accused Ristić of threatening Vučić, while Ristić's supporters decried this charge as tabloid sensationalism and a diversionary tactic.^[54][55]

During his first assembly term, Ristić was a member of the committee on Kosovo and Metohija; a deputy member of the committee on the economy, regional development, trade, tourism, and energy; and a member of the parliamentary friendship groups with China and Russia.^[56] Like several other opposition parties, the Otadžbina movement began boycotting parliament in early 2019 and later boycotted the 2020 Serbian parliamentary election.^[57] Ristić's first term ended on 3 August 2020.

In February 2022, he announced that Otadžbina would support presidential candidate Zdravko Ponoš and the United for the Victory of Serbia coalition in the 2022 Serbian general election.^[58][59] Ristić was himself included in the twenty-sixth position on the coalition's electoral list, with an endorsement from the Party of Freedom and Justice (SSP), and was elected to a second term when the list won thirty-eight mandates.^[60] He now serves in a parliamentary group led by SSP vice-president Marinika Tepić.^[61] Because Otadžbina is not an official political party, he is recognized in the assembly as an independent.

Ristić is once again a member of the Serbian assembly's committee on Kosovo and Metohija and a deputy member of its committee on administrative, budgetary, mandate, and immunity issues.^[62] He has said that any responsible Serbian government would prioritize the return of displaced Serbs to Kosovo in its dialogues with the Priština authorities.^[63]

In August 2022, Ristić said that many Serb families in Kosovo were leaving the area due to increased threats from the Priština authorities and accused the Serbian government of contributing to the problem by its inaction.^[64]
