The Liaison Office led by Gao Siren backed the Chief Executive Tung Chee-hwa government to push forward the controversial legislation of the national security bill as stipulated in the Hong Kong Basic Law Article 23. It was criticised for its failure in reporting to Beijing accurately the massive discontent toward the Tung regime and failure in predicting the unprecedented 2003 July 1 massive demonstration against the national security bill. It was said that the Liaison Office was too close to the pro-Beijing Hong Kong elites and naturally provided over-positive reports on the HKSAR to Beijing. As a result, the central government removed and replaced a number of deputy directors of the Liaison Office. A spy scandal was also revealed which involved with the leak out of the confidential information of the Liaison Office to the British agents.
