China has overhauled regulations to grant foreign firms greater access to its financial sector that is worth trillion of dollars, including to banks, fund management, brokerages and insurance businesses in recent years.

Swiss lender UBS became the first to hold a majority stake in a China securities business under the new rules last year. Japanese brokerage Nomura Holdings got its green light last month.

"We will continue to invest in and fully support our business in the country, which has become a critical market for many of our domestic and global clients," said Jamie Dimon, Chairman and CEO of JP Morgan Chase, said in the press release on Wednesday.
