The secretaries-general of Japan's ruling parties will visit China in late December to attend an exchange gathering with the Chinese Communist Party, a source in the ruling coalition said Sunday.

Toshihiro Nikai of the conservative Liberal Democratic Party and Yoshihisa Inoue of Komeito may also meet with China's leadership, including President Xi Jinping, during the several-day visit from Dec. 24, the source said.

The plans of Nikai and Inoue were confirmed when the LDP secretary-general met with Chinese Ambassador to Japan Cheng Yonghua in Tokyo on Friday, the source added.
