Chinese Communist Party leader Jiang Zemin arrived Wednesday for a summit with President Mikhail Gorbachev in the first Moscow meeting of the leaders of the world's two largest Communist Parties in 34 years.

Before leaving Beijing, Jiang said the two nations would sign a pact ending decades-old disputes over the Siberian-Manchurian border.Jiang's trip was the first to the Soviet Union by a Chinese Communist Party general secretary since Mao Tse-tung did so in 1957. It reciprocates for the 1989 Sino-Soviet summit in Beijing that was upstaged by the Tiananmen Square pro-democracy protests.

Jiang was met at the airport by Soviet Vice President Gennady Yanaev and the Deputy General Secretary of the Communist Party, Vladimir Ivashko. The flags of both nations flew and an honor guard greeted the Chinese party chief.

Jiang was driven to the Kremlin by motorcade and was welcomed by Gorbachev in a ceremony in St. George's Hall. The official news agency Tass said the two leaders had a brief conversation.

Jiang's five-day mission began two years to the day after Gorbachev's arrival for what was billed as a symbolic burying of the hatchet between the Communist rivals after decades of political hostility and periodic border clashes.
