It's arguably not even extortion. Venezuela secures a loan via promises of discounted iron ore sales to China. They weren't able to produce the promised iron ore so they continue to owe money because they didn't hold up their end of the agreement. This is the normal operation of failing to fulfil your part of an agreement.

If China asked for something outside the deal that they weren't otherwise entitled to, like say "let me build a military base in Venezuela or else I'll recall the debt" then it's extortion.

Where's the blackmail? Do you know what blackmail is? Did you even read your own linked article? China and Venezuela made a deal where China would loan them money in exchange the sale of Iron ore at a heavily discounted rate. In the end Venezuela were unable to produce the iron ore quotas despite fuether investment from China intended to increase their productivity. So China doesn't get the Iron Ore they were promised and Venezuela still owes money to China because they didn't meet the Iron Ore Quota they promised.

Where's the blackmail?

Are we just throwing words around that we don't understand? What's the blackmail? China has in fact already written off billions in loans already, if anything it's their own ledgers that are going into the deep red.

ITT Americans assuming healthcare works the same as their country everywhere else.

The French also have nuclear subs and also submitted tenders for nuclear subs. Time will tell if the AUKUS deal delivers. I think there's already some delays. But Scomo's biggest fuck up is in diplomacy, apparently he didn't even have the balls to call Macron to tell him lol.
