Any significant private investment decision, foreign or domestic, is made after sound analysis like profitability, return on investment, security of investment, quality and skill of labor pool, size of and nearness to markets etc., No one thinks much of whether a Sharif has made an investment. This may be a minor psychological factor but not a serious issue. If Pakistan does not get enough investments, it is based on sound business analysis, not whether some famous person is investing.Pakistan is not an investment destination... it's a rape and plunder destination.
Here is the formula... it's actually very simple..
Borrow money from IMF World Bank, Asia Development Band, and plunder the money into offshore accounts. And the Pakistani slave population gets raped. Invite international rapists to do the same as the pakistani treasonous military establishment, political parties, and corrupt elites.
Rinse and repeat.
Nobody is sincere with Pakistan. Those that are sincere are jailed. Example, Imran Khan.
