Hi Jeff,
Hopefully you will find a traveler with a 525 chain tool. Failing that you will have to resort to third world caveman technique.
When I needed to remove a link from a stretched chain on a rental bike in Costa Rice, this consisted of stopping at a roadside transmission repair shop where the owner Señor Pollo cut the chain off with a metal blade in an angle grinder, carefully ground the heads of chain rivet, used a hollow transmission input shaft against one side of the chain while he used a ground down pin punch to drive the pins out of the chain, remove a link, reassemble on the bike and had me hold a block of steel on one side of the chain while he carefully peened over the pin.
I'm not saying you should do this, more as information for someone slightly more desperate who may read this.
525 DID chains and tools can be rare as hen's teeth in the third world. More likely in Tashkent than a village in the mountains though.
I should think that a large C-clamp could be modified to work as a pin press in a pinch.
Others may have ideas.
Best luck.
Kindest regards,
John Downs
