All of the nations below China Such as Loas and Nam could go with China for the simple fact they do not want to be invaded. Russia has like 1/5 of the Chinese Economy and India has around half of the size. However China has more man power than any nation in the world. around 1.2 Billion People. If You get yourself a good draft going on in China and send the women to the facotoreis you can get some stuff done. Saudi Arabia could also go Nuetral, However Most Likly (I hate to say it) OPEC would make a decision for the major oil producing nations for simple fact that if they sold to China then Russia would get mad and if they sold to Russia china would get made.
