The Iran-backed Houthi militants of Yemen claimed responsibility Wednesday for a missile strike on a Saudi-flagged oil tanker in the Red Sea, escalating the risk to commercial shipping in the region and threatening to topple precarious progress in U.S.-Iran talks this week.

U.S. and Middle East officials said Tuesday that they were zeroing in on a deal with Iran to reopen the Strait of Hormuz. Secretary of State Marco Rubio pointed to progress, while Iranian officials said they were engaged in consultations with Oman, the neutral sultanate situated across the critical Persian Gulf shipping corridor.

It remains to be seen how the Houthi attacks occurring on the other side of the region will affect the U.S.-Iran negotiations. Regional officials say a potential Strait of Hormuz deal between Iran and Oman calls for ships to enter the Persian Gulf through an Iranian-controlled route and exit through an Omani-controlled route. It is not clear whether the Trump administration would accept the deal, which Iran says would be contingent on the U.S. lifting its blockade of Iranian ports.

Ukraine’s acting Foreign Minister Andrii Sybiha warned that Russia is trying to turn the Black Sea into a “second Strait of Hormuz,” saying Moscow’s attacks on Ukrainian ports are a campaign of “economic and humanitarian terror” that has essentially halted the movement of Ukrainian vessels through key trade routes toward the Mediterranean during the height of the agricultural harvest season. 

Threat Status Special Correspondent Guillaume Ptak reports in a dispatch from Kyiv that Ukrainian officials, traders and analysts estimate the country has already lost about one-third of its grain export capacity through Black Sea ports. Even cargo that continues to move becomes less profitable, with higher freight and insurance costs burdening Ukrainian exporters and farmers whose margins have already been squeezed by damaged infrastructure, expensive energy, labor shortages and lost farmland.

Ukrainian forces have answered Russia’s assault with their own attacks on Russian ships and maritime logistics in the Black Sea and Sea of Azov. The campaign has forced restrictions at Russian grain terminals and a ban on nighttime vessel movements at Novorossiysk, showing that maritime insecurity is spreading across the region.

Chinese Communist Party leaders said Wednesday that Beijing is imposing new restrictions on exports of Chinese drones to the U.S. and banning Chinese companies from engaging in trade or other activities with six American entities, including Applied DNA Sciences Inc. and the nongovernmental group Human Rights in China.

The Associated Press reports that officials in Beijing said the restrictions are in response to recent moves by Washington, including a ban by the U.S. Federal Communications Commission on imports of Chinese drones and the Department of Homeland Security’s decision to add 43 Chinese companies to the Uyghur Forced Labor Prevention Act entity list blocking imports of goods made with forced labor.

Tensions appear to be rising between the world’s two biggest economies ahead of an expected U.S. visit by Chinese President Xi Jinping in September for the annual U.N. General Assembly gathering. The latest developments come after signs of warming U.S.-China ties following President Trump’s visit and summit with Mr. Xi in Beijing in May.

North Korean troops and munitions “beef up Russia’s war against Ukraine,” while Russia “provides Pyongyang with sophisticated technology for its missiles, drones, satellites and submarines,” writes Clifford D. May, who notes that Iran has “sent Moscow drones” and that Russia has reportedly repaid the favor by providing Tehran with intelligence for targeting U.S. bases in the Middle East.

“Beijing is believed to give Moscow microelectronics for ballistic, cruise and hypersonic missiles,” Mr. May, founder and president of the Foundation for Defense of Democracies and a Threat Status contributor, writes in his latest column for The Washington Times. “Credible reports say Beijing now plans to send Tehran hundreds of portable shoulder-launched surface-to-air missiles capable of shooting down American aircraft. Discounted Iranian oil keeps Chinese refineries running.

“Do you see a pattern?” he writes. “Several years ago, Waller Newell — perhaps the world’s leading scholar on tyrants throughout history — observed the increasing alignment among America’s four principal adversaries.”

Retired U.S. Army Lt. Gen. Keith Kellogg writes in an op-ed for The Times that “you cannot prosecute a war like a business deal.

“War is too difficult to leave to chair-bound critics, people who lack an understanding of the principles of conflict or those who contemplate dollar signs rather than strategy,” writes Gen. Kellogg, a former National Security Council chief of staff now with the America First Policy Institute.

“This is especially true of proactive military action, or a war of choice. This is also why this war must be won, not managed,” he writes. “Wars of choice carry a higher threshold. Choosing to go is different from being forced to go or acting in self-defense; this is why winning matters even more. Losing a war of choice erodes deterrence more rapidly and diminishes a nation’s ability to project power.”
