China needed CPEC more than Pakistan..Pakistan should have told China, "you are welcome tobuild the infra use them and pay tolls/fee to us " till x years and after that they will be ours (like all BOOT projects works) ..China would have happily done ..instead China gave loans to Pakistan,built infra/roads for its use (most part) and purpose..with its own material ,men and machinery ..they got duties and tax exemption and even brought prisoners from China to work as free labour
Most of the CPEC 'investments ' has never hit the SBP.reserves ,.rather the machinery,raw material,-the construction cost ..which again done by Chinese companies, are invoiced /billed to Govt of Pakistan as Debt
If the project has to be successful the Chinese have to relocate manufacturing to Pakistan and use as export hub,China wins
If the project fails to take off -Still China wins , as everything is billed on Pakistan as Loan
Pakistan should have negotiated well and made COEC to its favor .Instead of orange lines,should have asked Chinese to set up industrial zones with export oriented companies and CPEC as BOLT/BOOT method
