What was the ping-pong diplomacy and what were its effects? plz

Ping-pong diplomacy refers to the visit by table tennis players of the United States and China to each others' countries, which gave way to normalizing the diplomatic relations between the two nations.

EFFECTS

* On April 14, 1971, the United Stated lifted a trade embargo against China, which had been there since twenty years.

* China won for itself a legitimate position in the United Nations in the October vote. It also soon established diplomatic relations with other countries.

Explanation:

It all began when, in the year 1971, American table tennis players had gone to Nagoya, Japan, to play the World Table Tennis Championship. Here, one of the players, Glenn Cowan, missed the bus to get back to the hotel, and he was asked by a Chinese player to board their bus instead. In the bus, the leader of the Chinese team, Zhuang Zedong, gifted Cowan a silk brocade showing the Fuchun Mountains. The next day, Glenn presented a red, white, and blue shirt in return, which had a peace emblem on it, and the words 'let it be'.

Mao Zedong, on reading about this 'gift exchange' in the newspapers, had mentioned, "Zhuang Zedong not only plays good ping-pong but knows how to conduct diplomacy as well." On this background, Mao asked the Foreign Ministry to send an invitation out to the American players to visit China. PRC wanted its unfriendly neighbors to take notice of the possible change in alliances, which was why it initiated contact with the United States. The U.S. took it as an opportunity, too.
