Xi and Trump’s White House summit tests US-China stability as UK warns Iran

The White House state dinner on Thursday night was a study in diplomatic theatre. Chinese President Xi Jinping and US President Donald Trump, two leaders who have spent years trading barbs over trade, technology and Taiwan, stood side by side in the East Room, exchanging toasts and professions of friendship. "We’ve never gotten along better," Trump declared, a claim that would have been unthinkable just 18 months ago, when the two nations were locked in a tariff war and a race to dominate artificial intelligence. Yet the warmth of the occasion belied the underlying tensions. Xi’s speech carried a pointed message: the world’s two largest economies, he said, must "act as responsible powers together." The phrasing was deliberate—a reminder that cooperation is not a choice but a necessity, even as both nations continue to jockey for influence in the Pacific and beyond.

The summit comes at a precarious moment. The US and China are still grappling with the fallout from last year’s semiconductor export controls, which crippled China’s tech sector and prompted Beijing to accelerate its own chip production. Meanwhile, Taiwan remains a flashpoint, with both sides conducting military drills near the island in recent months. Against this backdrop, the White House event was less about resolving differences than about managing them. As one senior US official told the BBC, "This isn’t a reset. It’s damage control." The question now is whether the fragile détente can hold—or if the next crisis is already in the making.

UK draws a red line with Iran over threats on British soil

While Washington sought to stabilise its relationship with Beijing, London issued a stark warning to Tehran. Foreign Secretary David Miliband summoned Iran’s ambassador on Thursday to deliver an unambiguous message: the UK will not tolerate "hostile activity" from Iranian-linked groups on British soil. The move follows a series of incidents targeting the Jewish community in the UK, including a foiled plot to attack a synagogue in London last month. According to British intelligence, the operatives behind the plot had ties to Iran’s Islamic Revolutionary Guard Corps (IRGC).

Miliband’s statement was unusually direct. "The UK’s resolve to combat these threats is unwavering," he said, adding that London would "take all necessary measures" to protect its citizens. The warning comes as Iran faces growing isolation. The US has reimposed sanctions on Tehran’s oil exports, and the EU is considering fresh restrictions over Iran’s support for proxy groups in the Middle East. Yet Iran has shown little sign of backing down. In a speech earlier this week, Supreme Leader Ali Khamenei accused Western nations of "hypocrisy" and vowed to "resist foreign pressure."

For the UK, the stakes are high. The Jewish community has reported a sharp rise in antisemitic incidents since the start of the Gaza war last year, and British officials fear that Iran is seeking to exploit the tensions. The government has already increased security at Jewish schools and synagogues, but Miliband’s warning suggests a more muscular response could be on the horizon. As one Whitehall source put it, "This isn’t just about sending a message. It’s about preparing for the possibility of escalation."

Ethiopia and Djibouti’s $600m pipeline: energy security or geopolitical gamble?

On the other side of the world, a different kind of power play is unfolding. Africa’s richest man, Aliko Dangote, has partnered with the governments of Ethiopia and Djibouti to build a $600 million fuel pipeline linking Djibouti’s port to landlocked Ethiopia. The project, announced on Wednesday, is designed to reduce Ethiopia’s reliance on imported fuel—a critical vulnerability for a nation that has faced chronic shortages in recent years. The pipeline will also create thousands of jobs in Djibouti, a small but strategically vital country that serves as a gateway to the Red Sea.

Yet the deal is not without risks. Ethiopia remains one of the most politically unstable nations in the region, with ongoing conflicts in the Tigray and Amhara regions. The pipeline could become a target for rebel groups, and its success hinges on the ability of both governments to maintain security along its route. There are also concerns about Djibouti’s growing dependence on Ethiopia. The two nations have a history of tense relations, and Djibouti’s economy is already heavily reliant on foreign military bases, including those of the US, China and France.

For Dangote, the pipeline is the latest in a series of high-stakes investments across Africa. The Nigerian billionaire has built a fortune in cement and oil refining, and he has positioned himself as a key player in the continent’s energy transition. But his critics argue that his projects often benefit elites more than ordinary citizens. In Ethiopia, where fuel subsidies have been a major source of public discontent, the pipeline could become a lightning rod for protests if prices remain high.

What this means for global stability

The events of the past 24 hours offer a snapshot of a world in flux. The US and China are attempting to stabilise their relationship, but the underlying tensions remain. The UK is drawing a line with Iran, but Tehran shows no sign of backing down. And in the Horn of Africa, a $600 million pipeline could reshape energy security—or become another casualty of regional instability.

What ties these stories together is the fragility of the status quo. The US-China summit may have been cordial, but it did little to address the structural competition between the two powers. The UK’s warning to Iran is a reminder that old conflicts are far from resolved. And the Ethiopia-Djibouti pipeline underscores the fact that economic development in Africa is often hostage to geopolitical rivalries.

For now, the world’s major powers are managing crises rather than solving them. The question is how long that can last.
