The Japan International Cooperation Agency's office in China will remain open even after Tokyo's decades-old official development aid to the world's most populous country came to an end at the end of the current fiscal year on Thursday.

The Japanese government has determined that keeping the JICA office in Beijing open is necessary to better grasp China's new role as a major provider of economic assistance to developing countries, officials said.

Japan's official development assistance to China started in December 1979 and has contributed to an improvement in infrastructure and helping China rise to its current status as the world's second-largest economic power.
