Playing on Chieftan Huge map at marathon! Help would be appreciated as I'm Portugal and Trying to take out the Chinese and their vassals!:)

Really not sure what the problem is here... :confused:

If you want to know what you do, then load four tanks or so into a transport and land them behind the Chinese city of Tianjin, which is on the west coast.

Use your cool bombers to bomb down the defences of the city and then use your tanks to squash the riflemen inside. You can then airlift some defence in I think. If not, just bring it over in a transport.

From there, station your bombers in your new city and just work your way south through all of China's cities. China's vassal is negligible, so don't worry about him.

Again, sorry if the answer isn't very good, but you're asking an odd question. You have lots of brilliant cities with stuff going on that I can't even understand, and since you've already killed a civ I thought something simple like a beach landing would be a piece of cake.
