As Presidents Barack Obama and Xi Jinping prepare for their upcoming meeting in California this week, Ian Bremmer and Jon Hunstman Jr. discuss the ways in which they must seize the opportunity to improve relations or risk seeing bilateral relations sour for the next decade.

As the two Presidents of China and the United States prepare to meet, Ruan Zongze writes that a co-operative Sino-US relationship will help the world advance towards a better future; on the contrary, their confrontation will lead to global retrogression.

The world should be optimistic ahead of the Obama-Xi summit in California. The two-day meeting will likely feature conversation about issues such as cyber-security and the trade. However, the main goal will be for the two statesmen to become familiar and establish a working relationship so they can pursue future goals both for their countries and for the international community.

The casual style of the summit at the Sunnylands estate, without much diplomatic protocol, offers a unique opportunity, writes Shen Dingli. Instead of mutual suspicion, China and the US should jointly open a new window at Sunnylands and breathe the air of freshly discovered trust.

The meeting between the American and Chinese presidents in June is the most important summit meeting on the diplomatic calendar this year, writes David Shambaugh.

China and the United States of America have recently announced almost simultaneously the June 7-8 summit between President Xi Jinping and President Barack Obama at the Annenberg estate at Rancho Mirage, California, which has caught worldwide attention. No doubt, the forthcoming summit will have extraordinary importance to China-US relationship and to world stability and development.

Chinese President Xi Jinping will visit Trinidad and Tobago, Costa Rica and Mexico and hold a meeting with US President Barack Obama at Sunnylands, the Walter and Leonore Annenberg Estate in California. This will be a new important step in the full swing of Chinese diplomacy since the new leadership took office.

An earlier Xi-Obama summit, writes Qian Liwei, is expected to pave the way for a more positive, mature and predictable Sino-U.S. relations based on mutual respect, reciprocal benefit and win-win co-operation.

The dawn of the global financial crisis has reshaped the global landscape. Now, the United States faces a strategic decision to either embrace peace and development or continue to seek hegemonic superiority. As Wang Yusheng points out, embracing this new opportunity is key for stability in the international community.

Secretary Kerry recently outlined a US Dream in the Asia-Pacific. Su Xiaohui writes that to achieve China’s goal of a stronger relationship with the US, China should be included in the US Pacific dream.
