Taiwan on Saturday said that it is changing the name of its de-facto embassy in the U.S. amid the strongest relations between the sides in decades.
The foreign ministry tweeted that the Coordination Council for North American Affairs was being renamed the Taiwan Council for US Affairs.
The addition of the word Taiwan will likely be seen as very important, since it appears to drop the pretense that the council is non-diplomatic or political in nature.
Even when U.S. had severed formal diplomatic ties with Taiwan in 1979 in favor of Beijing, the sides retain close unofficial relations that have grown ever-closer in recent years, including stepped-up military-to-military contacts.
The American Institute in Taiwan, which is the unofficial U.S. embassy in Taipei, recently moved into a substantially larger, purpose-built complex in a suburb of the capital.
China objects to all diplomatic and military contacts between Taiwan and the US and has been stepping-up pressure on the island as it claims Taiwan as its own territory.
