I bought my Macbook Pro in China in 2021...
At first I thought you were OK because the "country where purchased" language in the Mac AppleCare coverage did not cause a wave of similar questions here until Summer 2022.
As I researched this, Apple's language about Apple restricting AppleCare+ service for Mac computers to the country of purchase is far older than I thought. This 2019 plan document for the US:
Before March 19, 2019
includes the "restrict" language; see Section 4.1.
This is a "fuzzy" area and beyond our scope here as other end users. So babowa is 100 % right: you must contact Apple to confirm your coverage. Have your AppleCare documents at hand.
The Chinese-language AppleCare documents are here listed by effective dates:

That page has date ranges for the evolving plans, so use the one that matches your purchase date.
