China’s interests in the Middle East are both structural and strategic. Structurally, China needs the natural resources of the region, whereas the United States—now the world’s largest oil producer—does not. China is also seeking new markets to absorb its excess industrial capacity, and sees the Middle East poised for growth after decades of wars, woeful infrastructure, and popular discontent. Strategically, together with Russia, China is taking advantage of the uncertainty produced by ever-shifting U.S. policies, including zero-sum prescriptions for Iran and Syria that are unlikely to produce desired outcomes anytime soon. Regional governments in turn have welcomed China’s embrace, and its offer of investment without pressure to politically reform or respect human rights.

China’s President Xi Jinping previewed this more assertive Middle East strategy in a landmark address in Cairo three years ago. There, he declared that China does not seek a “sphere of influence” in the region—even while sinking nearly $100 billion in investments there through ports, roads, and rail projects. He alleged China rejects “proxy” contests—even while concluding a strategic partnership with Iran, the main sponsor of proxies in the region. And he warned against “all forms of discrimination and prejudice against any specific ethnic group and religion”—even while reportedly forcing 1 million Muslims into reeducation camps in China’s Xinjiang province.

Such contradictions can be maintained only so long as traditional U.S. allies in the region now welcoming Chinese investment allow them to be maintained. These U.S. allies do not shy from asserting their broader interests with Washington or expressing disagreement where policies diverge, and it is time they do the same with Beijing.

As the United States questions Chinese investment and intentions, particularly in the areas of technology and ports such as Israel’s Haifa, it can also challenge traditional allies as to whether they are granting China a free ride on what remains a largely U.S.-led security architecture. Such an arrangement should be as unacceptable to American partners in the region as it is to Washington. At the very least, these partners, together with Washington, can demand that Beijing utilize its emerging influence—particularly with Tehran and Damascus—to pursue measures that promote longer-term stability.

This might include action in the following four areas.

First, China can pressure Tehran to pull back its proxies and formations from Syria that threaten Israel. Emerging voices in Beijing seem to recognize that some Iranian activities in Syria present risks to Israel—and that an Israeli-Iranian conflict would jeopardize China’s own position in the region. Recent commentary in the government-backed Global Times, for example, recommended that Iran pull back its proxies from Syria. Formalizing this policy would be in the mutual interests of Beijing, Washington, and even Moscow—which has implicitly recognized Israel’s right to defend itself against Iran’s import of offensive weapons systems into Syria.
