Good morning. We’re covering a potential agreement to allow aid into Gaza, China’s nuclear buildup and Ukraine’s wartime economy.

Plus South Korea’s protest culture.

The U.N. and Egypt lay the groundwork for Gaza aid

The U.N. has made progress on an agreement that lays the groundwork for humanitarian aid to enter Gaza from Egypt, two officials said, although the details of how and when the desperately needed food and medicine would be delivered were not immediately disclosed.

Under the agreement, international observers would inspect aid trucks before they enter Gaza to satisfy a demand by Israel, according to officials who spoke on condition of anonymity.

Previous reports of imminent agreements to ease the backup at Gaza’s border with Egypt — both for people and aid — have failed to materialize. Egypt said it would allow 20 aid trucks into the enclave, according to President Biden, but the timing is unclear. Hopes are high that the aid trucks will be able to cross into Gaza today, according to E.U. officials.

The toll: Gaza health officials said at a news conference that at least 3,785 people had been killed in the enclave since Oct. 7. The figures are believed to include casualties from the hospital explosion in Gaza City, for which Hamas and Israel blame each other. U.S. intelligence agencies estimate the blast killed between 100 and 300 people, but cautioned that their assessments could change.

Gazans are struggling to communicate with the outside world and each other, as Israeli airstrikes have badly damaged communications and power infrastructure.

Mobilization: Satellite imagery shows that hundreds of Israeli tanks and armored vehicles have gathered about four miles north of the Erez border crossing into northern Gaza, in preparation for a potential ground invasion. The crossing has been closed since Hamas fighters seized it on Oct. 7.

U.S. support: The U.S. Senate yesterday unanimously pledged to furnish Israel with security, diplomatic and intelligence assistance. President Biden is expected to request $100 billion for Israel, Ukraine and other crises from Congress by today.

China’s military is adding more nuclear warheads

China is continuing to build up its strategic nuclear arsenal and has most likely amassed 500 nuclear warheads as of May, the Pentagon said in a new report, an increase of about 100 over last year’s estimate. It remains on track to have more than 1,000 nuclear warheads by 2030, most of them for weapons capable of striking the continental U.S.

The most eye-catching evidence of China’s nuclear buildup in recent years has been three clusters of missile silos constructed last year in the deserts of northern China. At least some intercontinental ballistic missiles had been installed in them, the report said.

The U.S. has also recorded more “coercive and risky” air intercepts by the Chinese military in the Asia-Pacific region over the past two years than in the previous decade, including one that came as close as 10 feet to an American military plane, the Defense Department said in its annual report to Congress on China’s military might.

Ukraine’s economy rises as it adapts to war

There are signs that Ukraine’s economy is recovering, albeit modestly.

Though its economic output is still considerably smaller than before the war — the economy shrank by one-third after Russia’s full-scale invasion last year — it will grow by an estimated 3.5 percent this year, the World Bank predicts. The expansion is driven by a pickup in domestic spending and is underpinned by a steady flow of foreign financial aid.

Economists say it will take many years for Ukraine’s economy to return to prewar levels, and forecasts in a time of fierce fighting are bound to be uncertain. Still, local analysts and businesspeople say, a sense of resilience and relative stability has taken hold after nearly 20 months of war.
