A speech by a Japanese student peace ambassador at an international disarmament conference in Geneva in August was canceled due to pressure from the Chinese government, according to Japanese government sources.

The speech by a representative of high school student ambassadors calling for the abolition of nuclear weapons had been delivered at every annual Conference on Disarmament since 2014.

But at the 2017 gathering China objected, citing rules that allow only government officials to speak, the sources said Thursday.
