Many people know that Minimax is Chinese because their video generator has a super obviously Chinese name (Hailuo), and that's what they've been known for so far
It's best when they state it themselves, and we can also verify by third parties. Not stating it, or outright obscuring it is also information. The Hailuo name is definitely an indicator, but it could be Taiwanese or Singaporean as well, or just foreign branding, like Häagen-Dazs.
