CLAREMONT, CALIFORNIA –As Chinese President Xi Jinping begins his trip to the United States in Seattle, home to many of the world’s leading technology firms, most observers are looking ahead to his subsequent meeting with President Barack Obama. Can the summit reverse the downward spiral in US-China relations that began with Xi’s accession to power in 2013?

Few dispute that the world’s most important bilateral relationship is in deep trouble. From the US perspective, China’s reckless behavior in the South China Sea, unrestrained cyber attacks against American targets, protectionist economic policies, and escalating political repression at home have demolished the belief that a globally integrated China would be a responsible and cooperative partner. Indeed, recent Chinese actions directly challenge vital American interests and core values.

Chinese leaders, for their part, view America’s strategic "pivot to Asia” as a thinly veiled step to tighten its geopolitical containment of China. Moreover, they have become obsessed with US dominance in international finance and technology and, most important, America’s ideological commitment to liberal democracy, which they regard as an existential threat to the Chinese Communist Party (CCP).

The toxic mix of mutual mistrust and tit-for-tat behavior has brought Sino-American ties to their lowest point since the Tiananmen Square massacre of 1989. There is now widespread concern that the US and China may be headed for a new cold war.

For Xi, the stakes of his US trip could not be higher. To maintain his domestic image as a strong leader, he must stick to his nationalist rhetoric and policies. But he also needs to stabilize the all-important relationship with the US.

Judging by recent moves by China and the US, we can expect modest success in a few contentious areas. While such improvements, on their own, will not change the relationship’s adversarial dynamic, they may halt the deterioration in bilateral ties, at least for now.

On the eve of the summit, both the US and China took positive, albeit symbolic, steps to demonstrate their goodwill and improve the diplomatic atmosphere. The US extradited a low-level Chinese official to face corruption charges. The Obama administration also decided not to announce sanctions against Chinese entities and individuals allegedly involved in cyber attacks on American companies and government agencies.

For its part, China released a human-rights activist and dispatched a high-level delegation to the US to discuss cyber security. In fact, the two sides are reportedly negotiating a landmark deal that would prohibit cyber attacks against each other’s vital infrastructure. An agreement on the issue could be the most important outcome of the summit, although other types of cyber attacks are unlikely to be covered by it.

For China, the biggest prize is a bilateral investment treaty (BIT). In practical terms, a US-China BIT would make it easier for Chinese entities to invest and operate in the US and increase American firms’ access to Chinese markets.

Such a deal would be a near-term boon for Xi, because it would represent a vote of confidence by the US in China’s struggling economy. But the prospects for a BIT are uncertain, at best. The US Congress is deeply skeptical, and the American business community needs convincing as well. Both have been bitterly disappointed by China’s mercantilist trading policies after its accession to the World Trade Organization. Given how many contentious issues remain unresolved, an accord is unlikely during the summit.

The South China Sea dispute may prove to be the toughest diplomatic nut to crack. China has staked its national prestige and its leadership’s nationalist credentials on this issue, which means that Xi is likely to rebuff US demands that China cease all activities seen as militarizing its new artificial islands in disputed waters. The most that can be realistically expected is an insipid statement of the two sides’ agreement to disagree.

But the most politically sensitive topic for China has little to do with cyber security or the South China Sea. It is China’s ongoing crackdown on civil liberties and human rights.

Facing enormous domestic pressure, Obama has announced that human rights will be on the agenda of his summit with Xi. But Xi is unlikely to make any concessions, because doing so could damage his political standing within the CCP and undermine a central component of his political vision: the reassertion of political control over a dynamic society.

Ultimately, the key question looming over the summit is whether Xi will be able to offer enough to repair the damage done to Sino-US relations in recent years. To be sure, trying is better than doing nothing. But what really matters is whether, after the summit, China takes concrete actions that reflect a genuine shift from the policies that have fueled the deterioration in bilateral ties.
