And just this week... Taiwan's flag was removed from London's flag display.
The Republic of China, also known as Taiwan, competes in the Olympics as Chinese Taipei and uses a special flag just for the games.
It cannot use the Taiwanese flag or play its anthem at Olympic venues, as mandated by a 1981 accord with the International Olympics Committee, stemming from sovereignty disputes with China.
But Taiwan's flag hung over Regents Street in London along with 205 other flags of the countries represented in the Olympics. The flag display is run by a neighborhood civic group, not the Olympic committee.
Earlier this week, Taiwan's flag was removed, reported the Taipei Times.
There was no reason given for its removal. But the Central News Agency reported that Taiwan's Olympic flag will be placed on the street display, instead of its flag.
Calls to the Republic of China's Ministry of Foreign Affairs were not returned.
