China won the 15th NEC SuperGo by two matches to one on 18 May 2000 in Shanghai, but in the senior match Cho Chikun 9-dan, in a rare successful international outing, demolished China's Shao Weigang 9-dan 2-0 in two short games.

In the other two matches, China's newest teenage star Xu Shuxiang 5-dan scraped through to a 2-1 victory over fellow New Star Takao Shinji 6-dan with a 1.5 point win in the deciding game, while in the women's match Chinen Kaori 3-dan lost her unbeaten record in this event to Li Chunhua 4-dan.

The NEC Cup Japan-China Matches the current incarnation of the famous Japan-China Supergo series, which in turn was a formalisation of a series of goodwill exchanges in which the Japanese helped the Chinese pull themselves up to world level. Obviously it is sponsored by the Japanese electrical giant NEC, which also sponsors domestic events in the two countries. Co-sponsors include Asahi Shinbun and the respective go associations.

Initially, and for 11 terms, the event was a win-and-continue match in which one player from each side began. The weaker players played first. In this and each game thereafter, the loser dropped out and the winner continued to play the next man from the opposing side. The side left with at least one unbeaten player was deemed the winner. These games spanned a year or more, two being played in quick succession in each country in turn (to save on travelling costs), with sessions one or two months apart. The number of players in the starting line-ups varied from term to term, between six and nine.

In 1997 this format was changed drastically, but the numbering of the terms continued unbroken. The first term under the new system was Term 12.

The new system is a series of three matches, each a best-of-three. Match 1, the senior event, is a Supergo match between the winners of the NEC Cup in each country. Match 2 is between the winners of the NEC New Stars event in each country: the NEC Shun'ei in Japan and the NEC Xinxiu in China. Match 3 is between selected women's champions.

The winner of Match 1 receives 5 million yen, and the loser 2.5 million yen. The winner of the New Stars receives 3 million yen and the loser 1.5 million. In the women's match, the winner gets 1.5 million yen and the loser 750,000 yen.

Komi is 5.5 points with Japanese rules. Time limits are 3 hours each with 1 minute overtime. The matches are held alternately in Japan and China.
