"International pressure on these two regimes, Belarusian and Russian must be much stronger. I would even consider the chance to exclude these two countries from many international organizations, including the sport competitions that matter to them", he said.
According to him, the regimes in these countries "act in an inhumane fashion", and they do not consider anything but economic and political pressure.
Meanwhile, EU foreign ministers will widen sanctions on Belarus on November 15 to include airlines and travel agencies thought to involved in bringing migrants to the bloc's border, the European Union's foreign policy chief Josep Borrell said.
The EU has accused Belarus of encouraging migrants to come to its territory and pushing thousands of them to cross into Poland and other neighbouring EU states in retaliation for sanctions already imposed on Minsk.
Two diplomats said on Thursday the EU is considering imposing sanctions on Belarus' main airport in a bid to make it more difficult for airlines to bring in migrants.
