Its already a disaster. Back in 2013, PDF was like by 2018 or 2020, toll collections from CPEC trade will be good enough to pay back the $45 billion debt. They used to argue that China would divert all its west Asia and Africa trade through Pakistan. Now they are pleading with IMF for $6 billion loan and asking China to differ the loan repayment period. And add to that loan repayment was suspended for Pakistan for 2 years on the account of Corona by G20, which will still add more burden on their ex chequer.
It is very similar to how you guys think that over priced Padma bridge ($3.4 billion) will add 2-3% to GDP or that over priced Roppur nuclear plant ($13.5 billion is absurd) will solve the power crisis. BBS (Bangladesh Bull Shitting) agency kept increasing the GDP to a point where revenue to GDP ratio has fallen to about 8%, leaving little room to play with that number anymore. Lol.
