Thanks

Looks good to me.
Daijirin, koj, and nikk have まい written in katakana since it's loaned from Chinese.

The kokugos are all very specific that our sense 01 refers to historical China ("中国で、…").
e.g. kanjipedia: 昔、中国で外国と取り引きをするときの仲介業者。

The word "comprador" is also still used in English with the same meaning as our second sense.
https://en.wikipedia.org/wiki/Comprador
>> With the emergence or the re-emergence of globalization, the term "comprador" has reentered the lexicon to denote trading groups and classes in the developing world in subordinate but mutually-advantageous relationships with metropolitan capital.

The JEs only have one sense.

I'm not sure that we need two senses here. If we do, then sense 01 might need a [hist] tag.
