The swap is explicitly conditioned on countering “China’s interference in the territory,” according to Casa Rosada officials quoted in Argentine media. Bessent’s veiled threats included stipulations to halt financial deals between Buenos Aires and Beijing, effectively demanding that Milei sever Argentina’s $20 billion currency swap line with China, which remains partially active in an economy on financial life support.

Good reporting I was unaware of.

This currency/bond operation would essentially be neutral for Argentina, if China is bailed out by being able to sell its pesos to the US. I don't expect Milei to refuse Chinese help though. Still a bankster oligarchy needing future favours from administration is also putting up investment packages. They are not necessarily doing anyone else a favour if privatizing stuff cheaply with Milei help.
