How to improve Pawn promotion probability

In my economic view, there are 3 types of economic companies.

Pawn: Domestic companies which work in own countries

Minor and Major pieces: Big companies which earn moneys in foreign countries

King: Central centers in own countries

Then, how to improve Pawn promotion probability?

Supporting by Minor and Major pieces to Pawn may be good method.

For example, if pawns in USA want to earn in China markets, supporting by Tesla, Microsoft and other Minor and Major pieces will be good.

Conversely, if pawns in China want to earn in USA markets, supporting by Minor and Major pieces will be good.

I recalled Mercari company’s fault.

Mercari has tried to enter in USA markets only by itself, but it was failed.

Because it had no support from minor and major pieces in Japan, such as TOYOTA or SoftBank.
