Li believes, the treaty will strengthen bilateral ties and is a vital move in the direction of peace and friendship between China and Japan.
The state visit implies a thaw in the long-standing hostile relations between the two countries, which ensued from territorial disputes over East China Sea islands and grievances from World War II.
The hotline for senior military officials to communicate in the case of incidents involving their navies or air forces will be launched within 30 days under an agreement signed after Chinese Premier Li Keqiang met Japanese Prime Minister Shinzo Abe in Tokyo.
Relations between the two countries are "at a crucial stage to improve bilateral ties", Li told Abe, adding that the two neighbours should be partners rather than foes.
The two countries, Abe said at the reception, can jointly shoulder greater responsibility in resolving regional issues, such as jointly promoting infrastructure construction in Asia by setting up a trans-departmental committee. Tokyo's hosting of the 2020 Summer Olympic Games and China's hosting the 2022 Winter Olympic Games will provide opportunities to enhance communication among the public.
"China will also be able to learn from Japan's experience in finance and investment", Sun said.
The most recent previous official visit to Japan by a Chinese premier was the trip made by his predecessor Wen Jiabao in 2011.
The emperor also said he feels nostalgic, when recalling his first visit and the cordial welcome he had experienced.
The importance of bolstering economic interaction between the three countries was also underscored by South Korean President Moon Jae-in who stressed that such a collaboration would contribute substantially to improving the living standards of people in Japan, China and South Korea.
Oshima congratulated Li for his successful visit to Japan.
Chinese Premier Li Keqiang Thursday said that he hoped that China and Japan would carry forward the spirit of the China-Japan Treaty of Peace and Friendship to push for new progress in bilateral relations. China's peaceful development is vital to Japan as well as the region and the world, he said.
