Serbia is considering possible arbitration because of Pristina violation of the Central European Free Trade Agreement (CEFTA), Prime Minister Ana Brnabic said on Thursday.

“At this moment, that is the only way to protect Serbia’s interests and have everyone who signed the agreement face the consequences in line with the contract they signed,” she told reporters at the 2nd Digital Summit in Belgrade.

She said that Serbia as the CEFTA Secretariat to react to Pristina’s decision to impose 100 percent tariffs on goods from Serbia last November but that the reaction she hoped for did not happen. Brnabic said Pristina’s decision is a bad signal for regional cooperation, adding that Belgrade thought hard about signing the regional agreement to cut telephone roaming charges because it was not sure Pristina would not break it.

She said there was no part of the region which would be stable unless the entire region is stable. According to the prime minister, Serbia will invest however much time, energy and political capital is needed to achieve a stable, predictable, prosperous and safe region.
