I don't think China can provide you with F-16s or Euro Fighters, thus this limits your choices to only one country and also makes you dependent on them taking away your freedom. You believe you get cheap oil from Saudi or UAE and that is the stick which these countries can use against you, do you really believe there are freebies on the planet. Every country has their oil reserves, in case of a war for how long that oil reserves is going to last? The untapped oil or other mineral reserves count for sh!t unless they are extracted which cost billions of 'dollars'. In India we keep on hearing we have world's 98% of thorium reserves and soon we will be richest country in the world yadla yadla but real world doesn't work that way. When it's dependability upon China, Saudi or US you can bet that you are in trouble. In real world there are only self interests, thus a weak currency for a export oriented economy and a strong one for an import oriented one is and will be the healthy norm and not the vice versa.
