Hong: In my opinion, the unique achievements of Hu's current visit to the US will not only be limited to promoting Sino-US relations. What is more worthy of attention is two "byproducts" of this visit.

The first byproduct is to dispel the anti-China words and deeds of neighboring countries and regions. Since 2010, most of China's neighboring countries and regions thought that the Sino-US relations were at low ebb. Therefore, they considered taking advantages of this opportunity and took the chance to launch various anti-China diplomatic and military actions.

Hu's visit will make neighboring countries and regions realize their misjudging of Sino-US relations. Sino-US strategic interests are of more common than divergent aspects, which will help suppress risky behaviors of these countries and regions.

The second byproduct is to strengthen China's public diplomacy. Hu's unprecedented visit includes two important carriers of China's public diplomacy: the Confucius Institute in Chicago and the US branch of the Wanxiang Group, a private Chinese corporation.

Hu will demonstrate to mainstream US society China's emphasis on traditional culture and public diplomacy.

Zhao: The world can be stable only when Sino-US relations are stable, because the future framework of the world will rely on Sino-US cooperation to solve the most important international issues while the G20 deals more extensive issues and a number of regional and functional organizations play their roles.

The most important subject now is to resolve bilateral differences and solve sensitive problems instead of seeking consensus. Nowadays, the US is the representative of developed countries, while China is the representative of emerging economies. Cooperation between the two is pivotal in motivating a new round of world economic recovery. Instead of Sino-US bilateral problems, the big subject for both countries is world economy and stability.

Pang: One of the keys to the future stability and development of Sino-US relations is whether Sino-US economic relations can achieve a fundamental transformation. Currently, such transformation seems difficult. But its success depends on our new thinking.

After the financial crisis, the US economic trends should be seen as a strategic opportunity for China to develop its relations with the US.

If Obama wants to win reelection, the key is to achieve substantial economic recovery, which makes him more willing to deal with China.

Zhao: We should focus on reinforcing the foundations of Sino-US diplomatic relations and pay special attention to those elements which are directly affected by Sino-US relations.

For instance, the yuan-dollar exchange rate is not only a constant bargaining point between the two governments, but also relates to the daily lives of people in both countries.

We should respect each other's legitimate interests and take the enhancement of trust and resolving of doubt as the foundation of all diplomatic efforts. Besides, we need to continuously expand the diplomatic consensus.

On some global issues of world economy recovery, international financial reform and global climate changes and some hot subjects related to regional peace and safety, both China and the US should find a diplomatic or problem solving consensus in order to make greater contributions to world peace and development.
