The four state-owned banks have deepened reforms and strengthened marketing and sales, the English-language newspaper quoted a report from the People's Bank of China as saying.
Their loan growth has accelerated while NPLs declined, the paper said.

To some degree, China sometimes has to readjust its pace of economic reform, for example the state-owned enterprises' restructuring, in accordance with how fast the banking reform has run.
