They have not shown this in their policies.
You are right, they have not shown it yet.
Let's hope they choose Pakistan over India, so that the Iran-Pakistan-China oil/gas pipeline can work.
Remember, if Iran chooses India, Iran is also working against Chinese interests, since the G8 nations currently voted who they "liked." Its obvious that the western nations will prop up India to go against China. This is what Bush also wanted.
America does not want an IPC pipeline to work.
Its up to China to make this work, because only China has the potential to stand up to America.
China could also get oil from Saudi Arabia, UAE, Qatar, and Kuwait through Gwadar. I also heard Saudi Arabia is moving away from America's camp.
