It is really clear, because either give up maduro, or eat sanction.Here's something basic I realize that seems to be forgotten for some reason.
Syria, Iran, Venezuela etc. Who's responsible for keeping these nations afloat?
The answer is simple. Themselves. Their own people plus their own government. Not anyone else. It doesn't matter how difficult, its their responsibility ultimately to think of a way.
If their own people and government can't be bothered to properly manage their own sovereignty, why should China do the lifting for them? That doesn't seem fair now does it? I'm hearing rumors that Maduro's own circle sold him out which is why there was little resistance. Why should China help someone who isn't serious about helping themselves?
And before you go oh but what about the US, what kind of investments did it make again? Most of them were easy mode countries that were already developed or in an easy environment. Where was its success with say Philippines, Iraq, Afghanistan or even South Vietnam? South Korea seems to be their only real high risk investment that paid off and right now they don't even have a choice since they put a base there way back in 1950.
China want oil, russia want to control oil prices, usa want to make money.
Maduro's regime was build on ousting the previous ruling elites, so they can nationalize all the oil profits. This process created a new ruling elite. This new ruling elite isnt gonna be rich or elite, if they are sanctioned everyday. this is the neccessary step for venezula to develop, maduro need to be sack. they need to open up the country for investment. China cant invest in there, if USA is blockading the whole country. venezula is a mountain jungle, and they need ocean access. well guess what, they are not cuba, they actually have something of value to sell.
new ruling elite sold out maduro, collected the bounty, and the country is now open up for business. the loser is maduro (he is gonna get hang to make the venezula expat lobby happy) and the previous ruling elites (because they are never getting their money back).
There is nothing personal or emotional in this. This is just business as usual. Maduro should have anticipated this, and gone into hiding.
