Sweden became NATO’s newest member on Thursday (7 March 2024), upon depositing its instrument of accession to the North Atlantic Treaty with the Government of the United States in Washington DC. With Sweden’s accession, NATO now counts 32 countries among its members.
What I'm saying is, if China and Russia truly cared about what the US is doing, they could choose to sanction the US and the West just like the West is doing to Russia right now. Like you say, China throwing their weight in would certainly have an influence.
Because the US geopolitical goals and actions, while often reprehensible, generally speaking aren't against Swedish interests, whereas Russia is a much more direct threat to Sweden.
Why does China keep appeasing the US by not sending weapons to support Russia?
