Japanese company executives are visiting China to boost economic ties between the two nations.
They will hold meetings with their Chinese counterparts and aim to help improve the climate for doing business.
The Tokyo-based Japan-China Economic Association has sent a delegation nearly every year since 1975.
A record 250 executives will be in Beijing for four days this time.
The business people say they want to discuss research and development of cutting-edge technologies and promote the protection of intellectual property.
The delegation is trying to arrange meetings with top Chinese leaders as well, including President Xi Jinping and Premier Li Keqiang.
The move comes amid signs of a thaw in diplomatic relations. The Chinese leaders had one-on-one talks with Japanese Prime Minister Shinzo Abe earlier this month.
