"This is a particular event organized by the Ukrainian president who is guilty of the deterioration of the democracy situation in Ukraine, the repressions against opposition, especially against Ukraine's former Prime Minister Yulia Tymoshenko and former Minister of Interior Affairs Yuriy Lutsenko," Tarasuyk, attending an international conference in Vilnius, told BNS on Thursday.
"I personally think that it is in the interest of democracy in Ukraine not to participate in the summit organized by the current authoritarian if not dictatorial regime in Ukraine," the opposition politician added.
Presidents of several European countries, including the Latvian and Estonian presidents, have recently refused to attend the Yalta summit. Lithuanian President Dalia Grybauskaitė said at a press conference on Tuesday she had not decided yet whether to go to Yalta.
Ukraine has recently come under criticism for its treatment of Tymoshenko in prison and is being urged to release the former prime minister.
Boycott football championship
Former Foreign Minister Boris Tarasyuk also called on European Union leaders to isolate Ukrainian President Viktor Yanukovych during the European Football Championship to be held in Ukraine in June.
In an interview to BNS, the opposition politician said the Ukrainian authorities would try to use the championship "to sell their story about democracy in Ukraine."
"We, the opposition, cannot pretend that nothing is happening in Ukraine and everything is fine," Tarasuyk, taking part in an international conference on democracy in Eastern Europe, said.
"The championship should take place, and the leaders of the European Union should not by any means go into contacts with the Ukrainian authorities in the margin of this championship," he said.
Some EU politicians plan to boycott the football championship in Ukraine in protest of the treatment of its treatment of former Prime Minister Yulia Tymoshenko.
President of the European Commission Jose Manuel Barroso said he would not go to the country. Austria also informed that no ministers from the country would travel to Ukraine.
