China is now the leading debt collector of the developing world. It took in $22 billion – more than 30 percent – of such payments this year, according to World Bank data. This marks a stark shift in China’s role following its lending surge under Beijing’s Belt and Road infrastructure program in the 2010s, according to a report released Monday by the Lowy Institute, an Australian think tank. China faces diplomatic pressure to restructure the debt, a burden for vulnerable economies that also face a retrenchment in Western aid and trade, the report says. – Staff

President Trump said he would delay tariffs on the EU. Mr. Trump said Sunday the U.S. would delay implementation of a 50% tariff on goods from the European Union from June 1 until July 9 to buy time for negotiations.

Ukraine and Russia completed a prisoner swap. An exchange Sunday saw each side bring home 303 more soldiers, after each released a total of nearly 700 combatants and civilians Friday and Saturday. The swap was the biggest since Russia’s all-out invasion of Ukraine in February 2022. It marked a rare moment of cooperation, after a massive Russian drone-and-missile attack. Mr. Trump leveled criticism at Russian President Vladimir Putin Sunday night, posting on social media that “something has happened to him.” – AP

The Pentagon placed new press restrictions. Secretary of Defense Pete Hegseth on Friday announced journalists must be escorted in unclassified areas, including ones open to them for decades under Republican and Democratic administrations. “While the Department remains committed to transparency, [it] is equally obligated to protect [classified intelligence] and sensitive information,” Mr. Hegseth said in a memo. The Pentagon Press Association called the move a “direct attack on freedom of the press.” – Staff

Harvard keeps pushing back on the U.S. administration. The university sued Friday over the administration’s revocation of the Ivy League school’s ability to enroll foreign students, which it called a “blatant violation” of federal laws. U.S. District Judge Allison Burroughs also temporarily blocked the Trump administration’s move. She scheduled hearings for Tuesday and Thursday to consider next steps in the case. – Reuters

The fall of Bashar al-Assad’s regime in Syria is turning out to have been a geopolitical game changer. After a decade-and-a-half of turmoil and division, a new Arab world alignment is rising in the Middle East. It signals a shift in power away from Iran’s weakened “Axis of Resistance,” which once stretched from Iraq to Lebanon. Sunnis seeking stability and prosperity now have friendly governments in Beirut, Damascus, and Baghdad. And a new moderate alliance is burgeoning: an axis of cooperation that puts stability, economic cooperation, and prosperity first.

The United States operates the world’s largest and most complex air traffic control system with a very high degree of safety. But a fatal air crash outside Washington, D.C., in January and a serious telecommunications outage involving the Newark, New Jersey, airport this month have focused attention on a long-known problem: The system is old and understaffed, and showing cracks. We look at proposed $12.5 billion fixes, how long they might take, and how well they may work.

Across Central America, civil society organizations are making deep cuts and in some cases closing their doors. That affects not only the direct beneficiaries of services around access to water, food security, or citizen journalism. In a region beset by high homicide rates and corruption, many organizations that are losing funding are also losing key footing as the last line of defense for democratic values. That is emboldening some antidemocratic governments in the region.

An old-school method of testing – having students write answers in a pamphlet known as a blue book – was on the rise even before the advent of generative artificial intelligence. Since the pandemic, it’s been seen by many as a way to thwart cheating and ensure students think for themselves. Other old-fashioned efforts help as well. “I wander around” during a test, says one professor. “I try my best to discourage [cheating] by just ... looming and lurking.”

Along the coast of Fumba, a village in the Tanzanian archipelago of Zanzibar, Bisha Hamadi Makungu and 14 other women work as part of Pania Uchupe, a seaweed harvesting collective. Each harvest week, the women collect more than 17,000 pounds of a strain of red algae that can be made into soaps and cosmetics as well as hot sauce and juice. The collective’s name means “Let’s work hard to succeed” – and for 26 years, that work has sustained Ms. Makungu’s family.

Eight decades after the surrender of Nazi troops in Europe, German tanks were graciously received in the Baltic state of Lithuania on May 22. The day marked the official launch of the first permanent deployment of German forces on foreign soil since World War II. In a ceremony to honor the historic event, however, the mood was less about shared defense against the Russian threat to Europe. Rather, it was more about shared gratitude.

Lithuania’s president, Gitanas Nausėda, thanked the German soldiers for their service, promising the best possible living conditions. A recent poll showed 85% of Lithuanians support Germany’s commitment of 4,800 soldiers to the front-line NATO state – a nod to the success of German pacifism since the war.

For his part, the new German chancellor, Friedrich Merz, said he was “all the more grateful” to Lithuania for welcoming German troops with “respect and great hospitality,” given the “suffering that Nazi Germany brought” to the country.

“Hosting foreign troops on one’s own soil is not something to be taken for granted, especially here in Lithuania,” said Mr. Merz, the first chancellor to have served in the Bundeswehr, as the German armed forces are known.

“For us, too, and for the Bundeswehr in particular, today marks a step into a new era,” he said.

Germany began to take on to a heightened security role in Europe following the 2022 Russian invasion of Ukraine. But last year’s election of Donald Trump as U.S. president and the recent election of a more conservative government in Berlin under Mr. Merz have sped up German spending on defense and a greater sharing of military resources with NATO allies.

With the world’s third-largest economy, Germany now promises to build up Europe’s “strongest conventional army,” as Mr. Merz put it. That could take years and massive spending. Yet one big and necessary step is making sure allies accept the mantle of leadership in Europe that Germany is offering in their shared defense of freedom.

The May 22 ceremony marked such a strategic gesture. “This is a historic day,” Lithuania’s president said. “This is a day of trust, responsibility, and action.”
