In his address at the founding conference of the AIIB council on Saturday afternoon, Chinese Premier Li Keqiang said the operation of the new multinational development bank is "of positive and constructive significance for the global economic governance reform."

Hailing Asia "an engine" for the global economic growth, Li said the sustainable development of the Asian economy and regional economic integration rely on the infrastructure construction and connectivity, which would help facilitate the flow of trade, investment, personnel and information.

The aim of China initiating the AIIB is to widen financing channels, expand general needs and improve supply so as to bring along the common development in the region and promote world economic recovery with its own achievements, he said.

The premier called on the AIIB to integrate the China-proposed Belt and Road initiative with each country's development strategies, promote international cooperation on production capacity and innovate more modes to realize a diverse and inclusive cooperation.

Global leaders extended congratulations to the opening of the multilateral development bank.

"The ADB will cooperate closely with AIIB in supporting the development of the Asia Pacific region," said ADB President Takehiko Nakao in a congratulatory message to the opening of the AIIB.

"We will cooperate closely to provide support and constructive suggestions for the AIIB development," said Yoo Il-ho, deputy prime minister of the Republic of Korea at the opening ceremony.

China's Vice Finance Minister Shi Yaobin said in an interview with Xinhua that China does not intend to apply for financial support from AIIB in the initial stage.

"Though as the biggest shareholder of AIIB and the biggest developing country in the world, China is fully qualified to gain loans from the AIIB, but we made the decision mainly because that many other countries in the region are in more urgent need for infrastructure development," said Shi.

Shi said China holds 30.34 percent of the whole capital stock, with the first batch of capital stock worth 1.19 billion U.S. dollars already in place.

The AIIB was proposed by President Xi Jinping in October 2013. Two years later, the bank was formally established as the Articles of Agreement took effect on Dec. 25 last year.

As its name suggests, the AIIB will finance construction of infrastructures -- airports, mobile phone towers, railways and roads -- in Asia.

Amid the evolving trend of the global economic landscape, Xi expected the AIIB will help make the global economic governance system more just, equitable and effective.
