'Up to the world' to catch China

China's dominance has made world table tennis uncompetitive, but the only solution is for other nations to raise their games, the sport's top official said on Wednesday.

The Rio Olympic table tennis competition kicks off on Saturday with Chinese players once again heavily favored to sweep the gold medals in their national sport.

"China has dominated our sport and of course it is better if you have, let's say, a competition, and it was not (competitive) in the last world championships and the Olympics," International Table Tennis Federation president Thomas Weikert said.
