BEIJING -- The leaders of Russia and China pushed back against U.S. pressure Friday, declaring their opposition to any expansion of NATO and affirming that the island of Taiwan is part of China, as they met hours before the Winter Olympics kicked off in Beijing.
Russia's Vladimir Putin and China's Xi Jinping issued a statement highlighting what they called "interference in the internal affairs" of other states, as Russia amasses troops on its border with Ukraine and China hosts the global games.
"Some forces representing a minority on the world stage continue to advocate unilateral approaches to resolving international problems and resort to military policy," it said.
The two leaders are looking to project themselves as a counterweight to the U.S. and its allies, as China shows growing support for Moscow in its dispute with Ukraine that threatens to break into armed conflict.
Putin's presence makes him the highest-profile guest at the Beijing Games after the decision by the U.S., Britain and others not to send officials in protest of China's human-rights abuses and its treatment of Uyghurs and other Muslim minorities.
Meeting with Xi, Putin praised "unprecedented" close relations with China in opening remarks carried by Russian television.
Relations "are developing in a progressive way with a spirit of friendship and strategic partnership," Putin said. "They have indeed become unprecedented. It's an example of dignified relations that support mutual development."
Putin highlighted close economic ties, including a new contract to supply China with gas from eastern Russian.
"For our meeting today, our oilmen have prepared very good new solutions for the supply of hydrocarbons to the People's Republic of China, and another step forward has been taken in the gas industry," Putin said.
Russia has long been a key supplier of oil, gas and coal for China's economy, now the world's second-largest, along with foodstuffs and other raw materials.
China's state-run news agency reported the two leaders met at the Diaoyutai State Guesthouse, but gave no details. They did not appear to shake hands when greeting each other because of covid-19 precautions.
Putin also recalled his presence in Beijing for the 2008 Summer Olympics, and the Chinese delegation's attendance at Russia's 2014 Winter Games in Sochi, calling such exchanges "to a certain extent a tradition."
The discussions mark their first in-person meeting since 2019 and come as China and Russia increasingly align their foreign policies bilaterally and in world bodies such as the United Nations, in opposition to the U.S.-led bloc.
Leaders of the five former Soviet Central Asian nations, which have close ties with both Russia and China, all followed Putin's lead and are attending, along with other states that have political and economic interests with Beijing.
U.N. Secretary-General Antonio Guterres, World Health Organization Director Tedros Adhanom Ghebreyesus and Director General of the World Intellectual Property Organization Daren Tang were among other dignitaries who arrived Thursday.
A buildup of more than 100,000 Russian troops near Ukraine has fueled Western fears that Moscow is poised to invade its neighbor. Russia has denied planning an offensive but urged the U.S. and its allies to provide a binding pledge that NATO won't expand to Ukraine and other ex-Soviet nations or deploy weapons there, and roll back its forces from Eastern Europe -- demands rejected by the West.
Putin and Xi accused other countries and alliances of trying to obtain military advantage that worsens the security of others, citing both NATO and America's Indo-Pacific strategy of building closer ties with other countries in Asia.
"The parties oppose the further expansion of NATO, (and) call on the North Atlantic Alliance to abandon the ideological approaches of the Cold War," their statement said.
The statement also said Russia reaffirms that Taiwan is an integral part of China and opposes Taiwan independence in any form.
Russia and China have held a series of war games, including naval drills and patrols by long-range bombers over the Sea of Japan and the East China Sea. In August, Russian troops for the first time deployed to Chinese territory for joint maneuvers.
Putin has also noted that Russia has been sharing highly sensitive military technologies with China that helped significantly bolster its defense capability.
