Shanghai has terminated its sister city relationship with Prague after the Czech capital signed a similar agreement with Taipei.

The Shanghai government said Tuesday that the city is suspending all official contact with Prague for “repeated erroneous actions on major issues involving China’s core interests, such as Taiwan.” The Shanghai government also accused Prague of “openly challenging the one-China policy,” which it strongly condemns.

Prague’s mayor, Zdenek Hrib, signed a sister city partnership Monday with his counterpart in Taipei, Ko Wen-je, after announcing the move last month. Prague’s city council had voted in October to dissolve relations with Beijing over ideological differences.

Since assuming office in November 2018, the 38-year-old Czech mayor has repeatedly irked Beijing by voicing support for Taiwan and Tibet. (Image: Tuchong)
