How will China react to any move to introduce tougher sanctions on Iran if no progress is made in efforts to prevent it from developing nuclear weapons? If China blocks action in the United Nations Security Council, relations with America will be set back to a point where any G-2 talk will seem laughable.
但此外还有一个更值得忧虑，却尚未浮现的问题。那就是如果在制止伊朗发展核武器方面还是难以取得进展的话，中国将对更严厉的国际制裁作何反应。倘若中国阻挠在联合国安理会实施行动，那美国对此的反应将令任何 G-2 对话变成一场闹剧。
