No, I think you're making the classic mistake all readers make when viewing CPEC, they see it is as some monolithic megaproject or giant expressway from Gwadar to Khunjerab. It's not that at all, it's a big portfolio of investments, the impact spans many sectors, but most of them deal directly with the basic needs of Pakistanis, like mentioned a lot of the work is on infrastructure and energy production in the early harvest projects.
The financing aspect needs too be assessed to in order for you to get a better picture of China's motivations. If finances were China's primary motivations, they could easily have invested their cash elsewhere, at lower risk, and probably at better returns. Most of these CPEC projects have very low interest rates on sovereign guarantee, the rest is a mixture of still fairly cheap private debt or equity. And already they've shown willingness to restructure and help us with any debt burden issues without asking us to sign off any concessions. There's a lot of good will involved here from the Chinese side.
And besides just the money, there's a lot of political capital invested in CPEC from the Chinese side. Xi Jinping's legacy is heavily attached to BRI, the flagship project of which is CPEC. I see no reason to doubt the intentions of the Chinese, quite the opposite, we've only ever seen good will and reasons to be optimistic. So CPEC isn't a hegemonic project as you might think it is.
if finance is the primary motivation contracts would not signed in secrecy. Contracts would not be renegotiated.
Having said that the primary goal of CPEC and BRI projects are to deploy surplus Chinese finance, production capacity and labor. If CPEC is about economics Pakistan would see economic results by now. $60 billion is a lot of money for a puny economy like Pakistan
CPEC looks like a nice way to control Pakistan through debt
