How table tennis changed the world, 50 years on

It was50yearsago but Zhang Xielin still remembers vividlyhowa shaggy-haired Americantabletennisplayer stepped onto the Chinese team's bus, a chance encounter which would shape history.

It was theworldchampionships in Nagoya, Japan, and Glenn Cowan mistakenly hopped in with Zhang and his teammates -- an awkward moment because the United States and China were then deeply at odds.

"We wereonthe bus and were talking and laughing," Zhang, now 80, told AFP.

"But when we realised that an American had come onto the bus, we fell silent."

The Chinese tripleworldchampion Zhuang Zedong eventually came forward and famously broke the ice, giving Cowan a silk embroidery as a souvenir from China.

They did not know it at the time, but it was the spark for China and the United States to begin normalising relations, in what became known as 'ping-pongdiplomacy'.

Zhang, a doublesworldchampion and later China's coach, recalled: "Mr. Zhuang understood that there was a difference between the American people and the American government, and that we should be nice to American people, so he took the initiative to chat with Glenn."

Photographers captured Zhuang and a 19-year-old Cowan shaking hands and smiling.

"The newspaper came out the next day and it seemed that China and the United States were about to have a relationship," said Zhang.

Days later,onApril 10, 1971 the US team became the first Americans to step foot in China for nearly a quarter of a century when they were invited to play friendly matches in the country.

The thaw saw President Richard Nixon visit China in February 1972, and a Chinesetabletennissquad visit the US.

In 1979 formal relations were established between the two countries.

'Compete peacefully'

Yao Zhenxu played Cowan, who died in 2004, during the Americans' ground-breaking trip.

Yao still remembers the score, he won 21-12, 21-14, and says that Cowan thanked him afterwards for "a serious game".

The American team were vastly inferior to the Chinese, so the hosts sometimes let their visitors win points in the spirit of sportsmanship and goodwill.

Now 74, Yao says that it was only afterwards that he realised that he had played a part in something historic.

"Because ofping-pongdiplomacy wechangedtheworldorder, and the people of China and the United States started friendly exchanges," he said.

Yao appeared alongside Zhang in ShanghaionSaturday to mark50yearsofping-pongdiplomacy, with the city authorities hosting an event with speeches and friendly amateur matches.

But the anniversary comes at a time when relations between Washington and Beijing have deteriorated markedly over a number of issues, notably trade, the fate of China's Uyghur minority and a clampdown in Hong Kong.

In a recorded speech to mark the 50th anniversary, China's ambassador in Washington, Cui Tiankai, accused some in the US of "ideological bias and zero-sum thinking".

But he and Chinese state media took a largely positive tone, with Xinhua news agency hailingping-pongdiplomacy's "wonderful legacy".

Yao and Zhang hope that the spirit of 1971 can help shape future relations between theworld's top two economies for the better.

"Everyone knows that the relationship between China and the United States is a bit tense nowadays," said Yao.

"We hope that we can agree to disagree and keep friendly relations.

"Don't be afraid of competition, we can compete peacefully."
