I'm not very concerned about it, because the co-operation is not strong in the military domain. It's more in the economic domain, with China needing resources and Russia, as the largest country in the world, having abundant natural resources. That kind of co-operation, like the Shanghai Co-operation Organization and others, is primarily in the economic domain. I don't see the ideologies of the two countries meeting. Even during the Cold War, there was one version of Communism that was Russian and another version that was Chinese, and they didn't see eye to eye. There's so much that divides them, and there are even challenges on their borders. No, I don't actually see the danger of a renewed Warsaw Pact or alliances that could challenge the NATO alliance.
