Worryingly for Beijing, diplomats and analysts say, the Biden administration has got other democracies to toughen up to a rising, more globally assertive China on human rights and regional security issues like the disputed South China Sea.
"China has always resolutely opposed the U.S. side engaging in bloc politics along ideological lines, and ganging up to form anti-China cliques," the Chinese foreign ministry said in a statement to Reuters.
"We hope relevant countries see clearly their own interests...and are not reduced to being anti-China tools of the U.S."
After last month's stormy talks between top U.S. and Chinese diplomats in Anchorage, Beijing also appeared to engage more urgently with countries like Russia, Iran and North Korea, which are also on the wrong end of U.S.-led sanctions.
COLD COMFORT
"China is very worried about U.S. alliance diplomacy," said Li Mingjiang, associate professor at the S. Rajaratnam School of International Studies in Singapore, pointing to what he calls attempts to "huddle for warmth" with governments shunned by the West.
Days after the Alaska meeting, the Chinese government's top diplomat, State Councillor Wang Yi, received Russia's foreign minister Sergei Lavrov, who called for Moscow and Beijing to push back against what he called the West's ideological agenda.
A week later, Wang flew to Iran and signed a 25-year economic pact, which Renmin University professor Shi Yinhong said "effectively exposes every Chinese company participating to direct or indirect U.S. sanctions."
President Xi Jinping, meanwhile, exchanged messages with North Korean leader Kim Jong Un, calling for a deeper partnership with another country whose ambitions for nuclear arms has drawn sanctions.
China is also wooing its economically dependent neighbours. Wang hosted foreign ministers from Indonesia, Malaysia, the Philippines, Singapore and South Korea in China's southeastern Fujian province in recent weeks.
Li said Beijing will be holding out promises to help these countries revive their economies after the COVID-19 pandemic, making them think twice about siding with the United States.
After Philippines diplomats and generals accused China of sending militia-manned vessels into their waters, President Rodrigo Duterte said he was not going to let territorial disputes in the South China Sea get in the way of working with China on vaccines and economic recovery.
BUILDING BLOCS
Biden has continued to pressure Beijing on many of the same issues the Trump administration did, but with a more alliance-focused strategy.
At a meeting between Biden and Japanese Prime Minister Yoshihide Suga on Friday, the two countries presented a united front against China's assertiveness, on issues ranging from the disputed East China Sea islands known as Senkaku in Japan and Diaoyu in China, to rights issues in China's Hong Kong and Xinjiang region.
Last month, the United States, the European Union, Britain and Canada imposed coordinated sanctions over reports of forced labour in China's western Xinjiang region, while over a dozen countries jointly accused China of withholding information from an investigation into the origin of the COVID-19 pandemic.
Germany, Britain, the Netherlands, Canada and France all recently joined the United States in sending warships through the disputed South China Sea, or announced plans to do so.
Washington also said it wants a "coordinated approach" with allies on whether to participate in the 2022 Winter Olympics in Beijing, amid concerns over human rights violations, particularly related to the treatment of Uighurs and other Muslim minorities in Xinjiang.
BREAKING THE 'CLIQUE'
China has responded angrily to shows of unity by Washington's allies, with its diplomats dubbing Japan a "vassal" and Canada's Prime Minister Justin Trudeau a "running dog" of the United States.
China's strategy to weaken this unity revolves around encouraging U.S. allies to engage independently with Beijing, and put the economic benefits first, while punishing them if they engage in joint-action against China.
Beijing responded to the EU's sanctions of Chinese officials over Xinjiang with disproportionately harsh counter-sanctions, analysts said, potentially torpedoing a long-awaited investment agreement.
Janka Oertel, director of the Asia Programme at the European Council on Foreign Relations, believes Beijing is prepared to sacrifice economic benefits for core interests if they are threatened by the U.S.-EU alliance.
Xi drove home the message in a recent phone call with German Chancellor Angela Merkel, telling her that he hoped "the EU will make a correct judgment on its independence".
But China still needs European technology and investment, said Joerg Wuttke, president of the European Chamber of Commerce in China.
"They still talk to us, despite the sanctions, business keeps going, and that's very reassuring."
Beijing has not given up persuading Washington that cooperation is better than competition, as demonstrated last week when it assured U.S. climate envoy John Kerry of support for Biden's virtual climate summit this week.
"China hopes Washington can appreciate that it is in U.S. interests to have China as a friend rather than as a foe," said Wang Wen, a professor at the Chongyang Institute of the Renmin University of China.
