"Some states sent their influential people to the UNESCO General Conference in Paris, they gathered representatives of several countries and exerted pressure on them," Aleksandar Vucic said.
He added that some of these countries changed their approach toward Kosovo membership at the last moment.
"For example, we spoke with a representative of Tajikistan some 40 minutes before the voting and he confirmed that he was going to vote against Kosovo membership. But then he did not attend the procedure, probably Turkey played its role there," the prime minister pointed out.
According to Vucic, several representatives of African and Asian states explicitly confirmed that they came under pressure over the voting on Kosovo.
Kosovo declared independence from Serbia in 2008 and is recognized by 108 UN member states. Belgrade considers Kosovo to be part of its territory.
