China says it hopes first joint Sino-Japanese history study can enhance mutual understanding regarding history and each other.

Chinese Foreign Ministry spokesman Qin Gang made the remark at a press briefing on Tuesday in Beijing.

He says through studying relations between China and Japan over the past 2,000 years and modern and World War II history, each country will better understand their histories objectively and establish a strong base for the future development of Sino-Japanese relations.

"We've always emphasized the strong basis for Sino-Japanese relations is to look at and treat historical issues correctly. If only historical issues are handled properly, Sino-Japanese relations will grow in a healthy manner. Otherwise, it will meet difficulties and obstacles."

The joint history study kicked off Tuesday in Beijing. Each country has appointed a 10-member team to conduct research.

Chinese President Hu Jintao and Japanese Prime Minister Shinzo Abe agreed in October to begin joint history research by the end of the year.

The two nations' foreign ministers also agreed to release the outcome of the study by the end of 2008.
