Lithuania on Monday summoned China's ambassador over the involvement of embassy staff in an incident at a rally in Vilnius last month backing Hong Kong's pro-democracy protesters.
Embassy staff "were involved in organising unlawful actions" when counter-demonstrators approached the rally, the foreign ministry said.
On August 23, more than a hundred Lithuanians linked hands in the capital's central square, in solidarity with Hong Kong activists holding a similar demonstration on the same day.
