Every year a lot of smartphones are released, most of them get a international edition but sometimes there are very good edition limited to a specific market. Why they do that?

For example recently OnePlus announces its OnePlus series 9 phones:

• One Plus 9, international availability
  
• One Plus 9Pro, international availability
  
• One Plus 9R, india exclusive
  

9R is a cheaper phone with almost the same feature, except for the enthusiast ones such as advanced cameras and top gamma CPU... why non-india people can't get it?

Another example are the Samsung esotic colors, on China and Korea has been reported the availability of RED and PINK variants of their phones over the times, they just get released a bit later than their international variants.

What differences between a international phone and a region-specific region are:

• CSC partition, they can be adjusted buy flashing the international ROM
  
• Modem LTE frequencies, nowadays we almost uses all of the available, except for some China frequences
  

What they do this unfair market strategy? 
If I like RED color why I should be unable to get it? Only because I am not chinese/korean? It is crazy.

It's just companies to maxinize their income.Widely-accepted interests are considered while others are ignored.And maybe that's why phones are not very "colorful",because for some colors they saw no point in it.
For country-limited phones,another concern,yes,to broaden the market hold there .Eg.for africa countries phones are usually cheaper but less powerful.
Yes,you may call this a kind of discrimination,but well,if you want one,you have to accept that.
