9月10日，2015年夏季達沃斯在大連舉行。金磚國家新開發銀行副行長萊斯利·馬斯多普在會后接受和訊網專訪時表示，新開發銀行將與亞投行積極合作，探索新的商業模式，另外，新開發銀行的投資將主要集中在能源領域。

在談到與亞投行的關系時，馬斯多普稱，亞投行對于新發展銀行來說是一個非常重要的機構，兩者成立的時間都不長，但意圖相似，“我們完全不是競爭的關系，將來會在各方面開展合作”。他表示，此前已與亞投行行長金立群進行過會面，雙方將在今后共同尋找更快更高效的運行方式，探索新的商業模式。

馬斯多普還表示，新開發銀行在很多領域都有投資意向，但可能將主要集中在能源，特別是清潔能源方面。他認為，清潔能源的發展給許多金磚國家企業帶來了機會，因此，新開發銀行業將把能源投資放在第一位。除此之外，道路鐵路等基礎設施建設方面的投資也會陸續進行。馬斯多普稱，目前投資尚未正式開始，不過新開發銀行已經開始尋找并確立一些項目。（中國進出口網）
