The Trump-Xi summit in Beijing was intended to herald a new era of calmer US-China relations, but for Indonesia and much of Southeast Asia, the outcome has deepened unease. The meeting between President Donald Trump and President Xi Jinping, while heavy on symbolism, yielded few concrete achievements and exposed a dynamic where great-power stability may come at the expense of middle powers.
Trump departed Beijing with warm words but little to show. Xi, by contrast, secured several strategic wins. Reuters described the summit as producing “stability and stalemate”—a reset that was more about optics than substance. Behind closed doors, Xi reportedly warned Trump that mishandling Taiwan could lead to a “dangerous” conflict, and Trump notably avoided public comment on the issue afterward.
Xi introduced a new phrase to define the bilateral relationship: “constructive strategic stability,” replacing the Biden-era language of “strategic competition.” Reports indicate Trump agreed to this framing in principle, a semantic shift that carries real weight. For Jakarta, this suggests that Washington and Beijing are increasingly focused on managing their rivalry on mutually favorable terms, rather than resolving it.
The danger for Southeast Asia is that regional concerns—especially maritime security and the South China Sea—could become secondary to broader great-power stabilization. Indonesia has long resisted being trapped between the US and China, relying on strategic autonomy, ASEAN centrality, and nonalignment. But that balancing act becomes harder when great powers seek to reduce tensions through elite diplomacy while unresolved disputes fester.
Maritime Security and the South China Sea
The South China Sea is the clearest example. Although Indonesia officially insists it is not a claimant state, China’s “nine-dash line” overlaps with Jakarta’s exclusive economic zone around the Natuna Islands, making Indonesia an unwilling stakeholder alongside the Philippines, Malaysia, and Vietnam. Over the past decade, Indonesia has responded cautiously but firmly through maritime patrols, fisheries enforcement, and military modernization near Natuna.
What worries Jakarta is not the prospect of a secret US-China deal over the South China Sea—Trump is unlikely to formally concede Chinese claims. The concern is more subtle. A calmer US-China relationship could reduce international scrutiny of Chinese maritime pressure precisely as ASEAN negotiations over the South China Sea Code of Conduct enter a sensitive phase. China has consistently pushed for a weaker, more flexible code that limits external military involvement, particularly by the US and its allies. Several ASEAN states want stronger legal guarantees grounded in international law and the 2016 arbitral ruling at The Hague, which rejected Beijing’s expansive claims.
If Washington now prioritizes “constructive strategic stability” over maritime pushback, Beijing may feel emboldened to push harder for a softer, less enforceable agreement. That could directly weaken Indonesia’s strategic environment. As noted in our analysis of Indonesia's strategic drift, the country is increasingly caught between competing pressures.
Economic and Technological Fragmentation
The summit also carries major economic implications for Jakarta. Trump arrived in Beijing searching for quick wins, accompanied by prominent US business executives and focused on Boeing aircraft sales and investment. But he left without any reported major breakthroughs. There was no solution to rare earth supply disruptions, which remain critical for global manufacturing, semiconductors, and defense industries. China’s export controls on strategic rare earth materials remain largely intact. Similarly, there was no meaningful breakthrough on advanced Nvidia H200 chip sales to China, despite Nvidia CEO Jensen Huang joining the trip at the last minute.
For Indonesia, this matters because Southeast Asia is increasingly caught in the middle of technological fragmentation between the US and China. Jakarta hopes to attract investment into electric vehicles, battery processing, digital infrastructure, and AI-related industries. But if technological rivalry continues beneath the surface of diplomatic stability, Jakarta may face growing pressure to navigate incompatible supply chains and competing technology ecosystems. The Trump-Xi summit highlighted this asymmetry, with Xi focused on long-term positioning and Trump on short-term transactional gains.
The summit also revealed limits to Trump’s leverage. Xi appeared patient and confident, offering no meaningful indication that China would pressure Tehran or reduce its broader strategic partnerships. Despite speculation before the summit, there was no clear Chinese concession on Iran. This reinforced perceptions that Beijing entered the summit from a position of strength.
For Indonesia, the likely response will be deeper defensive nonalignment. Jakarta will continue strengthening maritime security around Natuna while avoiding overtly anti-China rhetoric. It will quietly expand security cooperation with Japan, Australia, and the US without formally joining containment efforts against Beijing. At the same time, Indonesia will contend with the economic and technological fragmentation that the summit has underscored, as the region’s middle powers navigate an increasingly complex great-power landscape.
