@J20!, I have not seen any American action so far to blockade Chinese trade, in SCS or anywhere else. USA is only saying freedom of navigation, which is as important for Chinese trade, as it is for trade of other countries. USA is not even China's enemy; as your fellow Chinese commentators have repeated said on this very forum. So when you talk about US bases in the same vein as Chinese controlled overseas ports, it cannot be due to USA. See I do not know what is the purpose. A Chinese ship or sub can very well refuel at Colombo. It does not need Hambantota. There is no great advantage Hambantota offers that Colombo does not. Except, just one, that Hambantota is isolated and can be controlled by Chinese Navy without any SL oversight. The same is with Gwadar which has no economic importance. Chinese trade cannot traverse the mighty Himalaya and land at Gwadar. A better route is through Russia. In reality Gwadar will never flourish as a civilian port.
