Brazil ready to join China's Asian Investment bank; (Argentina any moment)

The office of president Dilma Rousseff said “Brazil is very interested in participating in this initiative,” from the country's main trading partner

The Asian Infrastructure Investment Bank, AIIB, seen as a challenge to existing institutions the World Bank and Asian Development Bank, has drawn a cool response from the United States, despite which European U.S. allies including Britain, France, Germany and Italy have already announced they would join the bank.

 Other countries such as Turkey and South Korea have also said they would join. Brazil, China's top trading partner, said on Friday it would sign up and that there were no conditions set. “Brazil is very interested in participating in this initiative,” the office of President Dilma Rousseff said in a statement.

Argentina is also expected to join given the close political, financial, trade and economic links between the two governments, following the recent visit of president Cristina Fernández to Beijing.

Russian First Deputy Prime Minister Igor Shuvalov, speaking on Saturday at a forum in Boao on the southern Chinese island of Hainan, said the country plans to join the AIIB, according to the official Xinhua news agency.

Speaking at the same forum, Australian Finance Minister Mathias Cormann said the country was planning to apply to become a founding member, according to Xinhua.

And the Netherlands also plans to join, Dutch Prime Minister Mark Rutte said on his official Facebook page after a meeting with Chinese President Xi Jinping.

China's Finance Ministry said earlier on that Britain and Switzerland had been formally accepted as founding members of the AIIB, a day after Brazil accepted China's invitation to join.

China's Finance Ministry said Austria had also applied to join and had submitted its documents to China.

“We should push forward with the creation of a regional hub for financial co-operation,” Xi said at the forum, adding China should “strengthen pragmatic cooperation in monetary stability, investment, financing, credit rating and other fields.”

The AIIB has been seen as a significant setback to U.S. efforts to extend its influence in the Asia Pacific region to balance China's growing financial clout and assertiveness.
