'Champion of democracy' is a debated term. 'Champion of capitalism' is more accurate. But the zinger in American life is 'shared democratic values' among the people like 'opportunity', 'social mobility' etc. In Pakistan or Bangladesh, no lower class person arriving there with ten dollars in their pocket can become a millionaire. In the US it can happen (and did - I know a dozen or so examples personally). Yes even if you are black, yellow or purple. Equal opportunity for Sanghis, Jamatis, Musallis and Murtads. You learn to tolerate and respect each other because that is the way to move forward instead of killing each other and be unproductive. No one is better than anyone else. Except money of course. We in the subcontinent have a long way to go to reach that level.
Trump? Politically correct? I don't think so.
But to use your words, if we all have 'our preferences', then we don't have to have a universal rule of civility (non-discrimination) we have adopted under the United League of Nations. It's not 'do whatever we want because we want it'.
There is a UN declaration (charter) of human rights. Pays to read it sometimes.

Discrimination is banned under this declaration (charter). And those countries that don't abide by it (like South Africa which had institutionalized discrimination) is going to be sanctioned until they straighten up. I don't think Pakistan will survive if that type of sanction as a punishment for discriminatory behavior is imposed on the Pakistani Govt. I certainly hope not.
But who am I to say this? Look at what Chaiwala is getting away with (the US hardly raises a peep).
Wanting investors in a certain country has little to do with their ethnic mix or their racial background. I don't know about Pakistan - but I don't think Bangladeshis prefer only a certain nationality to come invest in that country. Rather it is investment proposals, which are evaluated on merits to the target country (Bangladesh), not which country they come from (Japan). The amount of investments in Bangladesh from China also amount in the hundreds of Billions of dollars as signed in the last two years. Most of the investments from these two countries have been in infrastructure.
But there have been investment from Norway as well, in both Pakistan and Bangladesh (TeleNor). There are Malaysian and Indian investments in all sorts of manufacturing in Bangladesh too.
When you talk about Nigeria (and I had no other way to compare), take a look at where Nigeria is compared to Pakistan. I would not look down on them. If one day they get to Europe's level, and they want to invest in Pakistan, you're saying you'll turn them down?
