Which Fu Manchu Film?

Can anyone help identify which Christopher Lee/Fu Manchu I have a vague memory of. I think it might be Vengeance Of… Im pretty sure it features the German co-production actor fleeing on a ship at some point or going on some sort of sea voyage possibly in the East, also it has a big brawl with sailors of various nationalities in a bar in some port or other.

Any ideas?

He wants to freeze the sea in one of them, does that ring any bells?

That’s the Castle of Fu Manchu!
