Unlike the organisations for more popular sports, the ITTF tends to recognise teams from generally unrecognised governing bodies for disputed territory. For example, it currently recognises the Table Tennis Federation of Kosovo even though Kosovo is excluded from most other sports. It recognised the People's Republic of China in 1953 and allowed some basic diplomacy[8][9] which lead to an opening for U.S. President Richard Nixon, called "Ping Pong Diplomacy", in the early 1970s.
