BlackRock wants to dominate the asset management business in China like it has in the U.S.

The world's largest asset manager, with $6 trillion under management, is aiming to become a leading player in China, which it thinks has the biggest growth opportunity in the industry in the next five years, BlackRock's chief, Larry Fink, revealed in his annual letter to shareholders on Monday.

"In China, which is one of the largest future growth opportunities for BlackRock, we are focused on building an onshore presence," Fink said. "Our goal is to become one of the country's leading global asset managers."

Despite the economic slowdown and the ongoing trade war, Fink still sees an "increasing demand" for "more diversified and long-term investment solutions" in China. Half of the asset growth over the next five years will come from Asia and largely China, Fink said in the letter.

BlackRock is "very engaged" with Chinese regulators in the process of building a "majority-controlled" business, Fink told the Financial Times in a story Monday.

"If anything the Chinese are looking for greater participation of global firms in their asset management space because they also have a growing retirement crisis," he told the FT.

The asset manager has recently become increasingly bullish on Chinese equity markets as the country plans to introduce a Nasdaq-style start-up board in Shanghai, pushing for new ways that private sector money can fund its domestic companies.
