“I think Russia will take retaliatory measures pointing Latvia to its place, and these measures will be painful for it,” Tsekov told RIA Novosti.

According to him, first of all, we can talk about economic measures.

Latvian Foreign Minister Edgar Rinkevich also said that changes would be made to the country's legislation, according to which, after obtaining Russian citizenship, residents of Latvia would not be given a residence permit and they would have to leave the country.
