China might be looking at a base in Vanuatu, because OBOR isn't just, on the sea side, to Africa and the Middle East, but also to Latin America, with China's growing economic links to Brazil, Argentina, Venezuela, and the rest of the continent. OBOR is going to be a global belt, with the land routes to Central Asia, Russia, Europe and the Middle East, sea based routes to the Middle East and Africa, and a sea based routes to Latin America, which by the way, is also a major supplier of food stuffs to China in a scale that rivals the US.
I believe that China is increasingly looking at itself as the maintainer of the global mercantile order that the US is now abandoning with its isolationist, protectionist policies. It is also moving into the position what a true symmetrical naval power is all about. By symmetrical I mean the three pillars, only one of which is military naval power, the other pillar is the merchant navy, and the third pillar, the shipbuilding industry. The US has lost two of these, although strongly holding on to one.
Historically the world's largest seaborne trading nation ends up building the world's largest navy to protect that trade.
And we see China moving up the value chain with an exceptionally high level of R&D spending (2.1% Of GDP), which no other middle-income country is anywhere near, and which places China in the company of high-income hi-tech countries. In the next 5-10 years, we should see China start spending more on R&D than the USA.
So whilst China is still somewhat protectionist now, soon it will have domestic hi-tech global companies that can stand on their own, in every industry.
So yes, it will be in China's interests to maintain the global mercantile order, as the USA finds that it doesn't benefit from it as much as China does.
