Quick access to the project from different countries?

Question

PostgreSQL

Hello. Interested in how to speed up the availability of the database from different countries, for example, Russian users get access to a vps located in the same country, users from China to a Chinese vps, so that the information is relevant for everyone at once. So far I see this picture: when adding information to the database of one country, it is also sent to other servers in other countries, but again, it takes time and the information may be out of sync, at least in record identifiers. It would be easier to maintain one database, but as practice has shown, it is very slow. Maybe there are tools for such solutions.

It is difficult to formulate the question correctly, maybe someone will understand)
