TASHKENT, Uzbekistan — Making his first trip abroad since a bloody crackdown on protesters, Uzbek President Islam Karimov left yesterday on a visit to China, which has provided a rare note of support for the authoritarian Central Asian leader.

Karimov, who has rebuffed international calls for an independent inquiry into the May 13 bloodshed, apparently looked to his trip to underline that China is on his side. Yesterday, Beijing said it "firmly" backed his actions in crushing anti-government demonstrators.

China is eager to tap into Central Asia's energy resources, and it has watched warily since the United States deployed troops to the region, including at an Uzbek base, after the Sept. 11, 2001, attacks.

Beijing also wants stability in the former Soviet states of Central Asia, a region that China — like Russia — considers a tinderbox of Islamic militancy that could spread to its own territory.

The Chinese and Uzbek governments said Karimov's visit was planned long before the May 13 uprising in the eastern Uzbek town of Andijan.

Western governments criticized Karimov for using force to put down the uprising. But China and Russia have been more supportive of Karimov's decision to act after armed men seized government buildings and broke into a jail to free 23 businessmen accused of Islamic extremism.

Uzbek officials said 169 people — mainly militants — were killed in Andijan. But rights activists said hundreds of protesters died and insisted many were unarmed civilians who were only voicing their opposition to Karimov's government and anger over economic woes.

An Uzbek activist, former physician Gulbakhor Turayeva, said yesterday that she saw about 500 bodies in the yard of an Andijan school the day after the violence. She said she counted 400 bodies before guards chased her away and she estimated there were 100 more. She said most of the dead were men.

Turayeva said another activist, whom she declined to identify, reported seeing 50 bodies, mostly women and children, at a college building on the same day. Other residents said some bodies were buried secretly in several sites outside Andijan, she said.

However, corroborating official claims of violence by protesters, Turayeva said she had seen demonstrators hurling rocks at the city prosecutor, Ganidjon Abdurakhimov, as he sought to calm tensions before troops moved in. She said Abdurakhimov apparently was killed by stones.

Uzbek officials failed to show up yesterday as foreign ministers and officials from NATO nations and 20 of their neighbors to the east began two days of discussions about stability in the Euro-Asian region. Swedish Foreign Minister Laila Freivalds, the host, said Karimov's government gave no reason for withdrawing.

The United States also has criticized the crackdown and said it hopes for more democracy in Uzbekistan. But China and Russia are lined up on the other side.

"We firmly support the efforts by the authorities of Uzbekistan to strike down the three forces of terrorism, separatism and extremism," Chinese Foreign Ministry spokesman Kong Quan said yesterday in Beijing.

Kong said China "supports the efforts by the Uzbekistan government to stabilize their domestic situation and their commitment to development of the country."

China stresses the importance of maintaining stability in Central Asia through the China-backed Shanghai Cooperation Organization, whose members include Russia, Kazakhstan, Uzbekistan, Kyrgyzstan and Tajikistan.

The group set up an anti-terrorism center in the Uzbek capital, Tashkent, although the move is viewed as largely symbolic.

China said ethnic Uighur separatists are fighting for an independent Islamic state in its western region of Xinjiang, about 120 miles from Andijan, and share Uzbekistan's Muslim religion and Turkic language roots. Foreign experts said Beijing is using the specter of terrorism as an excuse to tighten control there.
