Serbia and Ukraine have agreed to deepen economic cooperation, with both sides pledging to finalise a long-stalled free trade agreement by the end of the year as Serbian President Aleksandar Vucic hosted his Ukrainian counterpart, Volodymyr Zelenskyy, in Belgrade.

The commitment came on the final day of a two-day visit that concluded on Saturday, Zelenskyy’s first to Serbia since taking office in 2019. The two leaders have met several times previously, most recently in Kyiv on July 15.

Speaking at a joint news conference, Vucic said Serbia would support Ukraine’s bid to join the European Union and maintain its support for Ukraine’s territorial integrity, including territories seized by Russia since 2014.

Belgrade has, however, refused to impose sanctions on Russia, its longtime ally.

Ukraine, for its part, has not recognised Kosovo’s 2008 declaration of independence. Serbia considers Kosovo part of its territory.

“You have never heard a single bad word about our country, neither from Volodymyr Zelenskyy nor anyone else [in Ukraine], and I am extremely grateful to our Ukrainian friends for that,” Vucic said.

“Our cooperation is expanding and will become much bigger,” he told reporters, adding that Serbia would help rebuild Ukrainian cities damaged by Russia’s invasion.

Long-delayed free trade agreement

The proposed free trade agreement has been under discussion for more than two decades, with both countries now aiming to complete a deal by the end of the year.

The agreement is crucial to Serbia’s bid to join the World Trade Organization and is a prerequisite for its EU membership. Ukraine has blocked a deal since 2005 over quotas and tariffs affecting its agricultural sector.

Both leaders pointed to progress on the agreement as a sign of strengthening economic ties, alongside Serbian commitments to provide humanitarian aid and infrastructure and energy support to Ukraine this winter.

Zelenskyy said the two leaders had discussed joint infrastructure projects as well as cooperation on energy and food security before the winter, saying that “virtually not a single thermal power plant remains intact” in Ukraine because of Russian strikes.

He said Russian attacks had also damaged railway stations, hospitals, universities and civilian businesses, and thanked Serbia for preparing a new humanitarian aid package focused particularly on the medical and energy sectors.

“We are developing all formats of cooperation which can give our people … more resilience,” Zelenskyy said.

In a post on X on Saturday, Zelenskyy said he also discussed economic and logistics projects with Serbian Prime Minister Duro Macut, including the Danube Corridor and closer links between Ukraine, the Western Balkans and the EU.

Zelenskyy thanked Serbia for pledging 2 million euros ($2.3m) to support Ukraine’s energy sector.

The two countries also signed a memorandum on animal health and food safety, according to the Kyiv Post. The agreement was signed by Serbia’s Agriculture Minister Dragan Glamocic and Ukraine’s ambassador to Serbia, Oleksandr Lytvynenko.

Serbia balances EU ambitions and Russia ties

Vucic expressed doubts that either Serbia or Ukraine would secure rapid EU membership.

“I wish Ukraine every success, but this is not just a merit-based process,” he said, noting that the bloc has not admitted a new member since Croatia joined in 2013.

He also warned that he did not expect the war in Ukraine to end soon.

“I’m very afraid that we’re in for a very difficult winter – especially for Ukrainians,” Vucic said, according to the Kyiv Post.

Belgrade had condemned Russia’s full-scale invasion of Ukraine in 2022 and has supported Ukraine’s territorial integrity, but it has resisted joining Western sanctions against Moscow. Serbia also remains dependent on Russia for most of its gas.

At the same time, Serbia has sought to reduce some of its military dependence on Russia, including through an agreement to replace its ageing Soviet-era MiG-29 fighter jets with French Rafale aircraft.

The Kremlin has repeatedly accused Serbia of selling ammunition that ultimately reached Ukraine through intermediaries. Belgrade has denied supplying ammunition to Ukraine, but has said it sells ammunition to buyers around the world.

Vucic and Zelenskyy said military cooperation was not discussed during the visit.
