His in-depth research into monetary policy and practical policy recommendations gained the attention of policymakers, so much so that he was invited to join the PBOC in 1997. He was also the head of the State Administration of Foreign Exchange (SAFE) from 2009 to 2016.

During his record 15-year term, Mr Zhou won kudos for his management of the PBoC during the global financial crisis and his success at bringing the country's yuan currency to reserve-currency status.
