china don't concern that whether our friends are great countries or not,we are seeking for long term and reliable friends,we wouldn't force them to join a war for us,we wouldn't ask them to contain our opponents,every developing countries have good relationship with china (maybe except few others) , U.S have lots of so-call allies,but how many allies of U.S will still with them if they have a real war with a big country ,and you forgot russia also have the similar strategic interests with china in this area,maybe some russian are a little bit worried about china's rising,but which partner you think Russia prefer:China or U.S?
