BEIJING, Jan 5 (Reuters) - China will increase its credit support for the development and construction of rental housing, the central bank and the financial regulator said in suggestions on how to support the rental market issued on Friday.

China will support commercial banks in issuing financial bonds for housing leasing, and will steadily advance the pilot work for real estate investment trust funds, the People's Bank of China and China's National Financial Regulatory Administration said in a joint statement.

The country will also set upper limits on debt levels of various types of housing leasing companies and of real estate development companies that hold rental housing, it added. (Reporting by Twinnie Siu in Hong Kong and Ethan Wang in Beijing; Editing by Hugh Lawson)
