I heavily dislike that america just leaves treaties it does not like instead of improving them. Most smaller countries cannot use the same method.
If my country for instance were to do thay nobody would ship there any more because the billing system would be too complex and expensive and the market is just too small.
In the article they make it clear that they’ve indicated they intend to leave, in a year’s time as required by the treaty, if negotiations to bring China out of its old developing nation status don’t succeed.
There have been efforts and negotiations to get the UPU to reclassify China from developing nation status for quite a while now, to no avail. This is the final gambit in those negotiations.
It’s best if you don’t let your hatred of an administration color your perceptions such that you choose not to look at facts.
You are of course correct that in general the US for the last 2-3 decades has been at best schizophrenic about multilateral institutions it was originally instrumental in setting up, and at worst actively hostile.
But in this case, my understanding is that the US did attempt to renegotiate the postal treaty recently, rather than abandon it, without much success.
The exit isn’t finalized, so this could be seen as an (admittedly very formal) gambit in the larger overall negotiation process.
