Can the China-US Detente Last?

Competition can generate incentives for restraint, and restraint can create opportunities for further competition.

The recent thaw in China-U.S. relations – highlighted by reciprocal visits by President Donald Trump and Xi Jinping – raised the prospect of a more stable relationship between the world’s two largest powers. After years of escalating tariffs, technology restrictions, and strategic mistrust, both governments appear willing to step back from the brink. The emerging language of “constructive strategic stability” suggests that Washington and Beijing may be converging on the need to manage their rivalry rather than allow it to define every aspect of their relationship.

But agreement on the need to manage competition is not the same as agreement on its terms. The two sides may have reached a shared conclusion that escalation is too costly without resolving the underlying disputes that drove them toward confrontation in the first place. If so, the current detente could prove less a turning point than a temporary adjustment in a much longer strategic contest.

The history of Soviet-U.S. detente offers a useful way to understand this possibility – not because the China-U.S. relationship is destined to follow the same trajectory, but because it highlights a central problem of great power relations: the conditions that encourage rivals to seek restraint may also make that restraint difficult to sustain.

The current thaw cannot be understood in isolation. It is the latest stage in more than a decade of intensifying strategic competition between China and the United States.

The Obama administration’s “Pivot to Asia” signaled a stronger U.S. commitment to the region as China’s power grew. Washington presented its policy as an effort to sustain regional order, while Beijing increasingly viewed U.S. initiatives through the lens of strategic containment. Yet competition remained partly bounded by the hope that economic interdependence and diplomatic engagement could prevent rivalry from overwhelming the relationship.

The first Trump administration marked a more decisive turn. The 2018 trade war transformed economic grievances into a central instrument of strategic competition. The Biden administration subsequently retained much of the competitive framework while expanding restrictions in areas such as advanced technology. Across successive administrations, Washington’s approach increasingly treated China not simply as a difficult partner but as a long-term strategic competitor.

The escalation of 2025-26 exposed the limits of this approach. Tariffs and countermeasures, particularly China’s leverage over rare earths and other critical supply chains, demonstrated that both countries possess vulnerabilities the other can exploit. But the ability to impose costs does not necessarily translate into a sustainable strategic advantage. Escalation can inflict damage on the opponent while simultaneously disrupting domestic industries, unsettling markets, and narrowing the room for diplomatic maneuver.

This gave both governments incentives to pursue a pause. Washington wants to stabilize trade, reduce supply chain exposure, and avoid a prolonged confrontation that complicates its broader economic and strategic priorities. Beijing has reasons to ease external pressure, preserve access to important markets and technologies, and secure a more predictable environment for economic development.

Their objectives for the detente, however, might not be identical. Washington may see a truce as an opportunity to rebuild leverage and reduce dependence on Chinese inputs. Beijing may see it as an opportunity to protect its economic position, limit U.S. pressure, and consolidate gains made during the confrontation. Each side can welcome stability while preparing for the possibility that competition will intensify again.

The significance of “constructive strategic stability” therefore lies less in whether it signals a fundamental reconciliation than in what the two governments understand it to mean. Does stability imply shared limits on competition, or merely a shared interest in preventing competition from becoming unmanageable? The distinction will determine whether the current thaw can endure.

What Detente Can – and Cannot – Do

The Soviet-U.S. experience is instructive in this regard. During the Cold War, detente emerged not because Washington and Moscow overcame their ideological rivalry, but because both recognized the dangers and costs of unconstrained confrontation. Arms control negotiations and........
