Presidents Vladimir Putin and Hu Jintao signed a joint declaration after two days of talks calling for a stronger United Nations role in global affairs and opposing attempts "to impose models of social and political development from outside."

The two leaders also urged other states to renounce "striving for monopoly and domination in international affairs and attempts to divide nations into leaders and those being led."

While the declaration did not identify any specific country, it echoed similar veiled hints by Moscow and Beijing about U.S. policy in global affairs.

After decades of rivalry, Moscow and Beijing have developed what they call a strategic partnership since the 1991 Soviet collapse, pledging their adherence to a "multipolar world," a term that refers to their opposition to U.S. domination.

China and Russia share a concern about increased U.S. influence in Central Asia since the Sept. 11, 2001, attacks, which led to American troop deployments in Uzbekistan and Kyrgyzstan for operations in neighboring Afghanistan.

While Russia remains a U.S. ally in fighting terror, relations often have been strained by U.S. concerns about backtracking on democracy under Putin and Moscow's worries about what it sees as U.S. meddling in ex-Soviet republics. Russia also bristles at western calls for peace talks with rebels in Chechnya.

Beijing is unhappy about U.S. ties with Taiwan. Beijing claims Taiwan as part of its territory and says the island has no right to conduct foreign relations.

"We reinforced our mutual support on key issues like Taiwan and Chechnya which concern our vital interests," Hu said after the talks.

The two leaders gave an upbeat assessment on Russian-Chinese relations, which have flourished in recent years and were cemented in a border treaty ratified this year.

"We have set a solid foundation for friendship, trust and cooperation for Russia and China for a long time to come," Putin said Friday.

Moscow and Beijing dominate the Shanghai Cooperation Organization, a regional security grouping that also includes the ex-Soviet Central Asian nations of Uzbekistan, Kazakhstan, Kyrgyzstan and Tajikistan.

Uzbekistan's President Islam Karimov, facing Western criticism for his government's bloody suppression of a May uprising, has found staunch support in Moscow and Beijing.

After their meetings in Moscow, Putin and Hu were due to meet again Tuesday at the SCO summit in Kazakhstan.

"We are increasing coordination and cooperation on important regional and international issues, such as guaranteeing stability in Central Asia, the SCO, reform of the United Nations and the nuclear problem of the Korean Peninsula," Hu said.

The Russian and Chinese militaries are due to hold their first joint maneuvers later this year - which some observers have seen as Russia's response to cooling relations with the U.S. and other Western nations.

China has purchased billions of dollars worth of fighters, missiles, submarines and destroyers after the Soviet collapse, becoming the main customer for struggling Russian defense industries.

Now it is eager to tap into Russian oil and gas to fuel its booming economy, and has lobbied hard for priority access over Japan to an oil pipeline carrying Siberian crude to Asian markets.

Russian-Chinese trade amounted to about $20 billion last year, and Hu told the ITAR-Tass news agency that it could reach between $60 billion and $80 billion by 2010.
