The New Development Bank plans to co-finance infrastructure projects with the Asian Infrastructure Investment Bank along the Belt and Road economies after more members join in, the NDB's vice president said on Sunday.

"There will be unlimited opportunities to co-finance projects with the AIIB in the future along the Belt and Road, because we share so much in common while selecting projects," Leslie Maasdorp told China Daily during the Boao Forum for Asia.

One year older than its peer multilateral bank AIIB, the NDB was opened in Shanghai in 2015, founded by the BRICS emerging economies, which include Brazil, Russia, India, China and South Africa.
