For example the US financed its South America operations with drugs for a long time. US, Israel, Germany or Russia sells weapons under the table to other countries.
Venezuela's leaders are financed by drugs today, like Cuba and Bolivia.
US, Saudi Arabia, Russia, Turkey give money or weapons to people that destabilize other countries like Syria , Ukraine or Iran, Iraq or Afghanistan. Osama Bin Laden for example was paid by the US for a long time,like Hillary recognized.
In Iran and Congo or Egypt the US simply destroyed democracy killing their leaders in order to loot their countries, just like their predecesors.
Talking with Syrian refugees, it was usual for them to see some alien(no Syrians) group enter their villages with the newest weapons and Iphones and do things like killing all Christians or raping all women, they were financed by external powers.
If you are Chinese and have lots of money the UK will welcome you in any of their tax havens, of course, while the Chinese have made it illegal. Remember the British Empire financed itself with drugs(opium) and slaves for all its History.
If you are Germany Italy or Switzerland and the US imposes you ridiculous sanctions like those to North Stream 2 project, you will find a way to evade the control of foreign powers over your sovereign rights paying on alternative places than those controlled by the foreign power.
