In finance, one of the most important things is trust. NY, London and Hong Kong are financial centers because they have been in the game for so long and people trust them with money.
Without trust, the market collapses because people will no longer want to engage in business.
When it comes to finance stuff, I hope China is keeping a list of countries that have lost credibility and treat them as one. I don't expect military actions. But as a country that tries to screw over China in finances, I hope China will act equally harsh to it going for stuff in that field going forward.
