A Chinese Foreign Ministry spokesman said Tuesday that China hoped its strategic relationship with Japan would continue its stable development after Japan's ruling party suffered a setback in Upper House elections.

"The Upper House election is a domestic affair of Japan and China is not in the position to comment," said spokesman Qin Gang at a regular press briefing.

Nevertheless, Qin said he hoped the China-Japan strategic relationship of reciprocity would maintain a stable and continuous development.

Japan's ruling Democratic Party lost its majority in upper house elections on Sunday.
