THE HAGUE, Netherlands (AP) _ French Judge Gilbert Guillaume, an international air terrorism expert, has been elected president of the International Court of Justice, a spokeswoman said Tuesday.

Guillaume and vice president Shi Jiuyong of China, were chosen Monday by fellow judges and will serve three-year terms,said spokeswoman Laurence Blairon.

Guillaume, 69, replaces New York-born Stephen Schwebel, who resigned in December.

The 15-member court is the primary judicial organ of the United Nations. It handles disputes between sovereign states and relies on the Security Council to enforce its decisions.

Guillaume, who has been on the court since 1987, helped negotiate international air safety conventions and teaches about terrorism at the Hague Academy of International Law.

Jiuyong, a former international law professor at Beijing's Foreign Affairs College, started with the court in 1994.
