The deal they signed today is to open trade between them to maximum levels in agriculture, security, nuclear proliferation, trade and to work together to create new technologies for space travel, missiles and the internet. They also both just cosigned each other, Russia condemned the AUKUS pact in Asia-Pacific and China once again strongly called out NATO saying they started the war and that they should only be defensive in nature and that although the war should end, they support Russias right to self defense (so theyre basically cosigning Putin).
They also are both talking about US biolabs and weapons and saying the US should hurry up getting rid of its chemical weapons stockpile. They both said they are against US Space Force being created and theyre both backing up North Korea officially sating the US is the one not wanting to dialogue.
None of this sounds like China is plotting on Siberia fellas, yall gotta give that a rest were going into Cold War 2/World War 3 vs a New Axis, not Mad Max Thunderdome every nation for themselves
Xi is definitely little manning Vlad but it seems the Chinese need the Russians expertise to get ahead in the Space realm and develop hypersonic rockets.
