China's cautious approach to defusing the ongoing North Korean nuclear crisis underscores the dilemmas that exist in its difficult relationship with North Korea on the one hand and its interests with respect to the United States on the other. What worries China more is North Korea's ambition and intention to further continue its nuclear programme. Moreover, China faces a daunting task in tackling the increasing American pressure to intensify actions against North Korea as per the UNSC resolutions.

The North Korean act of conducting an underground nuclear test has exposed the inherent limitations of various international institutions. It has also posed a challenge for the US as to how to make China behave as a responsible 'stakeholder' in international politics. If Beijing could not restrain Kim Jong-Il's regime from flagrantly conducting a nuclear test in disregard of the combined opposition of the international community, Pyongyang has created a complex political atmosphere, which needs China to deliver considerably to bring the current crisis to an end.

The underground nuclear test conducted by North Korea yesterday has established it as the ninth member of the nuclear club. There had been speculation, particularly since the failed test of a long-range missile, that North Korea would move to a nuclear test. It had warned about the impending test, and quite simply had nothing to lose. From a North Korean point of view, it was clear that the failed missile test demonstrated weakness and another missile test in the near term was unlikely to reduce international pressure on the regime.

The speed and relative ease with which the Indo-US nuclear deal raced through the respective committees of Congress and the margin by which it was assented to by the House of Representatives on 27 July, scarcely four months after it was introduced in Congress, created the expectation that the same scenario would play out in the Senate. These hopes have been belied by the failure of the Senate to pass the Bill before it recessed for the mid-term elections.

On July 27, 2006, the US House of Representatives overwhelmingly passed the bill HR 5682 for United States and India Nuclear Co-operation Promotion Act of 2006. This bill was submitted to the House by its International Relations Committee, after modifying the bill HR 4974 which was referred to the House by the US Administration. The House in an "up-or-down vote" passed this bill by a wide margin, with 359 members voting for and 58 opposing it. A number of amendments seen as killers were defeated on the floor of the House.

After months of excruciating negotiations, testimonies and debates, the two crucial committees of the US Congress voted overwhelmingly in favour of the Indo-US nuclear agreement, setting the stage for a formal Congressional vote. The International Relations Committee of the House of Representatives approved a legislation favouring the agreement with a near three-fourths majority (37 to 5) on June 27. This was followed by a bigger mandate (16 to 2) in the Senate Foreign Relations Committee on June 29, thus ensuring a definite "yes" vote at the joint session of the Congress.
