Kosovo's government says it will put a 100-percent import tax on all goods imported from Serbia and Bosnia-Herzegovina as diplomatic tensions rise.

Wednesday's decision appears to be retaliation against what Deputy Prime Minister Enver Hoxhaj said was Serbia's ``aggressive campaign against Kosovo on the international stage.'' A day earlier, Kosovo failed to join Interpol because of what it claimed was campaigning by Serbia.

``That was a very aggressive stand from Serbia,'' Prime Minister Ramush Haradinaj told a news conference.

The tariffs come into power immediately and don't apply to international brands produced in the two neighboring countries.

Haradinaj said that Serbia and Bosnia had never respected the Central European Free Trade Agreement, or CEFTA, rules in the trade relations with Kosovo, causing significant financial losses.

Earlier this month, Kosovo introduced a 10-percent tax on goods from Serbia and Bosnia-Herzegovina, both of which haven't recognized Kosovo's 2008 independence.

Serbian President Aleksandar Vucic has called the national security council, Serbia's top body dealing with the military and police, to address the issue, according to state Tanjug news agency.

Despite simmering tensions between Serbia and Kosovo, business ties have grown and Serb imports to Kosovo amount to about 400 million euros ($460 million) a year, while Kosovo's exports to Serbia are much lower.

Serbian Trade Minister Rasim Ljajic said Kosovo's move came as a result of its failure to get an Interpol seat.

Bosnian Foreign Minister Igor Crnadak likewise called the tariff ``payback'' for the Interpol decision.

EU foreign policy chief Federica Mogherini called on Kosovo to revoke the decision, saying that ``is a clear violation of the Central European Free Trade Agreement (CEFTA) and of the spirit of the Stabilization and Association Agreement between the European Union and Kosovo.''

Zahir Tanin, head of the U.N. Mission in Kosovo, also expressed his ``concern regarding the potential impact on the people of Kosovo as well as the political implications on the dialogue and normalization of relations between Belgrade and Pristina.''

Kosovo and Serbia have been in European Union-mediated negotiations for seven years. The EU has told the two sides they must normalize relations as a precondition to entering the bloc. Vucic has said that Serbia wouldn't take part in the talks until Kosovo lifts the recently-introduced taxes.

``It is 20 years since the war, 10 years from independence, and Serbia has not shown the good will to normalize ties,'' Haradinaj said.
