BEIJING, March 1 (Xinhua) -- Chinese Foreign Ministry spokesman Qin Gang on Thursday reiterated that the proper handling of historical issue is the "key" factor for a healthy and stable development of China-Japan relations.

　　Qin made the remarks in response to a question concerning the visit of a delegation from Japan's Liberal Democratic Party (LDP) to the Chinese National Museum on Anti-Japanese War in Beijing on Thursday.

　　Qin said the two countries reached agreement on getting over obstacles in bilateral ties and promoting healthy development of relations during Japanese Prime Minister Shinzo Abe's ice-breaking China trip Last October.

　　Since then, leaders of the two countries met for several times. Premier Wen Jiabao is scheduled to visit Japan this April, Qin added.

　　China-Japan ties are back onto the track of sound development, Qin said, calling for both sides to cherish the hard-won achievement.

　　"We are ready to work with Japanese personages who treasure China-Japan relations, and make joint efforts to promote this relationship in a healthy and stable manner," he added.
