Based on what culture exactly? Can you name a single Chinese worldwide hit movie or TV show from the last 12 months?

I can think of only Korean Squid Game and a few Japanese anime shows that are somewhat successful.

Do Chinese movies even get distributed into places like India, Africa, South America as US produced stuff does?

  Like its predecessor, the film received highly positive reviews from critics, and achieved even greater commercial success at a gross of $2.2 billion worldwide against a production budget of US$80 million.

  Ne Zha 2 broke numerous box office records inside and outside China, including becoming the highest-grossing film in a single box office territory, the highest-grossing animated film, being the first adult animated film in this position, the highest-grossing non-English language film and the first animated film in history to cross the $2 billion mark, as well as being the highest-selling animated film based on ticket sales.

  It also ranks as the highest-grossing film of 2025 and the fifth-highest-grossing film of all time.

Having grandchildren made it hard to avoid.

As for China in Africa:
