President Biden is constructing and deepening new alliances to strengthen the U.S. position in its showdown with China, but he risks alienating longstanding allies in the process.

Why it matters: Biden heralded a new agreement to help Australia acquire nuclear submarines as part of a trilateral security pact with the U.K. and the U.S. as an "historic step" to update U.S. alliances to face new challenges. The message from French foreign minister, Jean-Yves Le Drian, was quite different.

The Italian government mandated on Thursday that all workers must show proof of vaccination, a negative COVID-19 test or recent recovery from infection, Reuters reports.

Potato, potahtoh. Tomato, tomahtoh. It’s a debate we owe to Peru, the third-largest country in South America, which gave the world its native potatoes and tomatoes among other foods.

Why it matters: Ancient Peruvians developed and planted thousands of crops, including quinoa, tomatoes, corn and potatoes — which are only indigenous to the Andes in South America. The Spanish then exported these crops around the world at a time when famine was common from Europe to Russia. Smithsonian Magazine credits Peru's potatoes with making the rise of the West possible.

Macau casino stocks imploded Wednesday on news that gaming companies on the island are now squarely in China's regulatory crosshairs.

North Korea tested a new "railway-borne missile system" during its latest launch on Wednesday, adding another option for its ballistic missile program, according to North Korea's state-run Korean Central News Agency.

Why it matters: The AUKUS partnership is a warning to China's government as the Biden administration moves to counter Beijing in the Indo-Pacific.

The International Criminal Court (ICC) formally authorized on Wednesday an official investigation into alleged crimes against humanity during Philippine President Rodrigo Duterte's war on drugs.

President Biden came into office with a plan for dealing with China that sounded great in theory but's failing in practice.

Why it matters: The idea was to confront China aggressively on a range of issues — from trade abuses to human rights — while working cooperatively on areas of mutual interest, including climate change. A new plan to help Australia acquire nuclear submarines makes that both-ways approach even less realistic.
