“Those erroneous remarks made by some Lithuanian politicians further undermine the bilateral relations between China and Lithuania, and damage the credibility of the Lithuanian country and the fundamental interests of its people,” the Office of the Chargé d'Affaires said in a press release.

Landsbergis was the only one among the European Union’s high-ranking politicians to publicly support Pelosi’s visit to Taiwan.

After the US House Speaker’s plane landed in Taipei, the Lithuanian foreign minister said that she “has opened the door to Taiwan much wider”.

"I am sure other defenders of freedom and democracy will be walking through very soon," he then tweeted.

According to Beijing, Lithuania “deliberately caters to certain countries and group forces, manipulates ideology and confrontation between the East and the West will only lead to conflict and confrontation”.

“Lithuania violates the one-China principle and basic norms governing international relations, and condones "Taiwan independence" separatist acts will only further escalate tensions across the Taiwan Strait and undermine regional peace and stability. Seeking “Taiwan independence” leads to a dead end, so does supporting “Taiwan independence,” the Office of the Chargé d'Affaires said.

It stressed that “there is only one China in the world” and Taiwan “is an inalienable part of China's territory”.

China has been holding huge drills encircling Taiwan since Thursday to protest this week's visit to the island by US House Speaker.

It was previously rare for military jets and ships to cross the median line, although Chinese incursions have become more common after Beijing declared in 2020 that the unofficial border no longer existed.

The median line is an unofficial but once largely adhered-to border that runs down the middle of the Taiwan Strait, which separates Taiwan and China.

Crossings of the line are sensitive because the Taiwan Strait is narrow, just 130 kilometers at its thinnest point, and incursions raise the risk of military accidents.
