BEIJING -- Chinese Premier Li Keqiang on Monday reaffirmed cooperation between the Asian Infrastructure Investment Bank (AIIB) and existing financial institutions.

The AIIB will take an open and inclusive attitude and be complementary to existing development banks, said Li at a meeting with the president of the Asian Development Bank (ADB) Takehiko Nakao .

The AIIB will strengthen the region's communication, social and economic development, Li said.

Nakao said the ADB was ready to cooperate with the AIIB.

Speaking of the support of the ADB for China's social and economic development, poverty reduction and regional economic cooperation, the premier pledged further partnership with ADB and called on it to play a bigger role in poverty reduction and development.

Britain, France, Germany, Italy, Luxembourg and Switzerland recently applied to join the AIIB as founding members, which already had 27 prospective founding members.

Nakao is in Beijing for the annual meeting of the China Development Forum, a platform for business and academic leaders to interact with China's top decision makers and economic planners.

This year's meeting has attracted more than a hundred CEOs from international corporations, experts and scholar, and leaders of international organizations.
