See for example Chinese websites, apart from the obvious different alphabet even the top websites are completely different than Western ones in terms of design.
You'd be fighting an uphill battle that can only be won with a mix of intangibles, patriotism and personal attacks against the character and validity of competitors which would let you hit because why the hell would Zuck or Musk care about some founder insulting them from Burma or Myanmar or Ethiopia .
You'd be running a much smaller operation compared to legacy social media but you'd be the King of that operation, both in terms of decision and equity ownership and speaking about that your exit (several years down the line) could be selling to the largest domestic ISP.
But I don't think it can be done if you yourself don't know the alphabet, culture and design culture of Myanmar, Vietnam, Ethiopia, Namibia, Tanzania etc.
Be ready to immerse yourself and go there, because you gotta go there if you want to do it.

Social media has different problems, one of which is the "two sided market" problem which hits it twice because users increase the value for other users and because of the user-advertiser connection. Another one is in funding and investment: frankly, European investors are "too smart for that shit", that is, Twitter and Facebook both IPOed before they had a business plan that made sense. There was a narrow time window that Silicon Valley investors would fund businesses like that but since then, even they won't.
