In what context? If it is about how it has made money...it is extremely relevant. as of this writing, nearly 91% of the revenue the movie has generated has come from China (approx: $280,500,000). The covers the cost of the movie and then some. If the context is in the movie quality, that is a completely different conversation.
The domestic box office (if you're American) tanked, hard. Opened in 2nd place opening weekend and then made about $4mill the next. It hasn't done well here in America, but money is money is money is money, and they couldn't (the movie's producers) care less where it came from, as long as copious amounts flow to them.
