The first response should always be to ask them to define the line between neo-colonialism and equitable exchange, and what would have to change about the exchange between China and Pakistan for it to not be neo-colonialism. Gotta nail those goal posts down before you take a punt or the posts will move.
You can pretty much guarantee that if China's deal with Pakistan doesn't count as a fair exchange, nothing does.
Only the port has been taken over in such a way
Yeah, as you suspect this is liberal media coverage distorting perspective with a very narrow scope. The port is a tiny part of the area that's going to benefit as a result of the development. The trouble with opposing the neo-colon argument is that we have to do as much research as people who do it as a full-time job to fill in the data and scope that was deliberately omitted.
