Hundreds, maybe thousands, of Tokyo-bound trips had been cancelled, but not for the Confucius Institute Headquarters in Beijing, which sent a vice-director to the Japanese capital to meet teachers and volunteers from the Confucius Institutes in Japan.
"You wouldn't believe it - there were only six people flying on a big plane to Japan that day," said Xu Lin, director-general of the Confucius Institute Headquarters, known as Hanban.
"The more two countries' ties deteriorate over political issues, the more important it is for Confucius Institutes to play a role in helping preserve and strengthen the rapport between the people of the two nations," Xu said.
Since the founding of the first Confucius Institute in Seoul eight years ago, the development of these organizations has ballooned beyond all expectations, especially in developed countries.
According to Xu, the non-government organization is designed to teach foreigners Chinese and immerse them in oriental culture.
