Despite tumultuous events in the Middle East, the financial gains offered to investors usually trump concerns about the region's stability, the chief executive of the Bahrain Economic Development Board (EDB) told CNBC Wednesday.

"Greed usually overcomes fear, investors do a risk-reward analysis and they've always seen the reward," Khalid Al Rumaihi told CNBC's Hadley Gamble.

"There's a 50 million population just in the Gulf, hyper capital income, massive investment infrastructure, that outweighs the conflicts that they might see in the region."

Al Rumaihi's comments come after President Donald Trump said the U.S. would withdraw from the Iranian nuclear deal, raising question marks for investors over the region's stability and its relations with Iran. Al Rumaihi said conflict was nothing new, however.

"We're not new to conflict and that's not going to change the dynamics we see and the potential for growth."

Al Rumaihi spoke to CNBC as the Gateway Gulf Investor Forum, organized by the EDB, got under way in the Bahraini capital Manama. The forum is centered around discussions and workshops on the region's economic transformation and investment opportunities, in Bahrain and beyond.

Over 500 global investors and business leaders are taking part, the EDB said, with the forum a way to explore opportunities being created by the economic transformation in the Gulf Cooperation Council (GCC).

Al Rumaihi said the region was at a turning point. "We think it's an inflection point, we want foreign investors to be a part of that change."
