"Amid setbacks and chronic challenges in almost every major region, Washington views South Korea as a linchpin on a global scale. From hosting the G20 summit in 2010 to preparing to host the next Nuclear Security Summit in 2012, South Korea has been establishing itself as a global partner in addressing common challenges, ranging from rebalancing the international economy to preventing the use of nuclear materials for terrorist attacks. For President Lee, the state visit is an important opportunity to demonstrate South Korea’s unique role as a bridge between the developed and developing countries."

On September 28, North Korean state media announced that Kim Jong-il's third son, Kim Jong-eun, was promoted to the rank of four-star general just prior to the opening of the Workers' Party of Korea conference. Kim Jong-eun was later named vice chairman of the Party's Central Military Commission at the conference. These important developments follow the late August meeting between Chinese President Hu Jintao and North Korean leader Kim Jong-il in Changchun, near the Sino-DPRK border, which appears to have cleared the way for this Party conference. After the meeting, both countries' state media reported the leaders' support for the rising generation of the Party — a clear reference to Kim Jong-eun.

"...if China continues to prioritise friendly commercial relations with North Korea and Iran, it will threaten its own long-term security. A chronically proliferating North Korea would provoke Japan to reassess the need for a nuclear deterrent, while a nuclear-armed Iran could destabilise the Gulf and global energy markets. Crafting an approach that includes a sustained US-China engagement to clarify each side's intent, provides for China's energy security and maintains a focus on the threat of nuclear proliferation in North Korea and Iran is more likely to achieve our shared non-proliferation goals."

"Beijing viewed North Korea's explosion of a nuclear device in October 2006 as not only an act of defiance to the international community and a threat to regional stability, but also an act of defiance toward China. Chinese officials admit that their toolbox for managing the North Korean nuclear weapons challenge must now include a combination of pressure and inducements."

Despite extensive diplomatic efforts to facilitate the six-party talks, domestic policy constraints, differing priorities, and conflicting historical analogies among each of the countries have brought vastly differing perspectives to the multilateral negotiating table.
