BEIJING — China on Wednesday released fresh details about a new financial regulatory body intended to calm a financial system that in recent years has endured a stock market crash, a huge exodus of money outside the country and the rapid accumulation of debt.

But the details may raise more questions than they answer, and could disappoint those looking for a strong hand to rein in the financial system underpinning the world’s second-largest economy.

Official Chinese media reported late Wednesday that a new Financial Stability and Development Committee had held its first meeting, nearly four months after President Xi Jinping ordered its creation. It said the meeting was led by Ma Kai, a 71-year-old vice premier.

At the meeting, Mr. Ma stressed that China’s financial system should serve the real economy, according to the official Xinhua news agency — namely, making money available to businesses that need it. He also stressed financial security, the report said.
