Japan and the United States plan to reaffirm the need to ensure fair governance and transparent management in a China-led regional development bank during summit talks between their leaders in Washington later this month, diplomatic sources said.

The two allies, in coordinating their positions during the April 28 talks between Prime Minister Shinzo Abe and U.S. President Barack Obama, aim to prevent Beijing from making arbitrary loans as a competitor for influence in infrastructure investment in Asia, the sources said on Thursday.

Japan and the United States are in concert in staying out of the Asian Infrastructure Investment Bank, citing concerns over the opaqueness of the institution's governance standards.
