On September 14, 2005, Chinese Foreign Minister Li Zhaoxing, on behalf of the Chinese government, signed the International Convention for the Suppression of Acts of Nuclear Terrorism during the "treaty event" held at the United Nations (UN) headquarters in New York.

In April this year the 59th UN General Assembly approved the International Convention for the Suppression of Acts of Nuclear Terrorism which is the 13th anti-terrorism convention of the UN and the first international accord aiming at fighting against nuclear terrorism. The document for the first time defines nuclear terrorist crimes, fills in gap in the existing anti-terrorism treaty system, helps improve the international legal framework on anti-terrorism and provides the legal guarantee to prevent and punish nuclear terrorist acts.

After Li Zhaoxing signed the Convention, Chinese Permanent Representative to the United Nations Wang Guangya told the reporter it is of special significance that China signs the document the first day it is open for signature. It shows the consistent position of the Chinese government of opposing terrorism in whatever form and supporting the improvement of international legal framework on anti-terrorism and demonstrates the determination of the Chinese government to be committed to taking tangible actions to fight against terrorism in accordance with related laws.

Wang said that after signing the International Convention for the Suppression of Acts of Nuclear Terrorism China will carefully consider the rectification of the pact and at the same time hopes more countries will consider signing and rectifying it so as to make it effective at the earliest date possible. It is prescribed that the Convention will become an international law with the rectification of the 22nd signing country.

On the same day, Li Zhaoxing, on behalf of the Chinese government, also signed the United Nations Convention on Jurisdictional Immunities of States and Their Property which, passed by the 59th UN General Assembly in 2004, defined the general principles of the jurisdictional immunities of states and their property in foreign courts and laid the foundation for unifying related legislature and practice of different countries.
