In February 1990, Guo was transferred to Beijing to serve as minister-level Vice Governor of the
People's Bank of China, the country's central bank. In this capacity, he supported the opening of the
Shanghai Stock Exchange and the
Shenzhen Stock Exchange. In July 1993, Guo was appointed Deputy Auditor-General of the
National Audit Office (NAO), and was soon promoted to Auditor-General in April 1994. After the National Audit Law was adopted in 1995, the NAO initiated an audit of 43 ministries and departments of the central government, including the
Ministry of Finance, the
General Administration of Customs, and the
State Taxation Administration. The audit uncovered systematic corruption in the government, but the results were not initially made public. A year after Guo stepped down from his position, Premier
Zhu Rongji published the report in 1999, disclosing many serious problems including the misuse of hydrological funds by the
Ministry of Water Resources. In March 1998, Guo became a member of the Standing Committee of the
9th National People's Congress, Deputy Director of the Congress's Finance and Economics Committee, and Founding Director of the Budget Committee. He was a member of the
13th and
14th Central Committee of the Chinese Communist Party. == Death ==
