It's not ancient China that long ago was the most powerful empire in the world but isolated themselves and got passed many times over by the West. This is a new deal. A new capitalist China in a global economy.
Just like US worked hard to secure oil and other raw materials and also build a "shield" to protect themselves (using economic and military allies against their rivals) so will China. They'd be fools not to. It secures their own future and their own homeland if everyone is dependant on them.
China is already positioning itself in Africa and Latin America.
