China condemned a visit by Estonian lawmakers to Taiwan last week as a violation of the country’s claim over the island, the latest point of tension between Beijing and the Baltic region.

A five-member delegation from the foreign affairs committee of Estonia’s parliament made a trip to Taiwan, where they met with President Lai Ching-te and other high-level officials. The group praised Estonia’s improving relations with Taiwan in recent years, saying in a statement that democracies must stand together and warning of the “threat of autocracies.”
