"We have an agreement on a free trade zone, concluded by the Russian and Yugoslavian governments. At present, as Serbia prepares to join the European Union, the European Commission wants it to abandon the agreement. So our concerns are completely justified," Medvedev stated at a session of the CIS Council of Heads of Government.
The accord, signed in August 2000, aims to deepen bilateral economic and trade cooperation as well as creating necessary conditions for the free movement of goods and capital.
