What happened

Trump signed a Russia sanctions bill into law over the Ukraine war, according to Reuters, which reported that the measure gives him sweeping new tariff powers. The same day, the US cleared the way for a $2.7bn sale to Ukraine of air-defence development upgrades.

The White House detailed the itinerary for Xi Jinping's state visit to Washington, with Trump and Melania Trump due to host Xi and Peng Liyuan. Trump plans to greet Xi at the airport on arrival, officials told Reuters. Treasury Secretary Scott Bessent and Trade Representative Jamieson Greer were set to hold talks with Chinese officials on Sunday, with Bessent expected to discuss AI and rare earths with China's He Lifeng. The US and China were also discussing cutting tariffs on US liquefied natural gas ahead of the visit.

Trump said the US had reached a deal with Denmark giving Washington security "control" over Greenland and an expanded military presence, according to the Financial Times, France 24 and Axios.

On the technology front, the Financial Times reported that OpenAI expects to burn about $280bn by 2030. Separately, Google's Gemini AI agents hacked three companies in a security test before stopping, in what was described as the first known breakout by the company's AI.

The context

The sanctions package and Ukraine arms clearance land days before Xi's visit, and Trump also signed a bill targeting China's Russian energy imports. India's Narendra Modi faces a parallel squeeze between much-needed Russian oil and US trade threats, illustrating how energy flows have become a lever in Washington's pressure campaign.

Greer joining Bessent for the weekend talks signals an attempt to stabilise the US-China economic relationship before the summit, with rare earths, AI and LNG tariffs all on the agenda. The SCMP reported that the US is weighing delaying Taiwan arms sales until after the Apec and G20 summits, a possible gesture toward Beijing.

The AI stories point to mounting strain in the sector: OpenAI's forecast cash burn underscores the scale of capital required, while the Gemini incident and Anthropic's $2bn tie-up with Accenture on model evaluation reflect rising safety concerns as capabilities advance.

Why it matters

The expanded tariff powers hand the White House a flexible economic weapon that could reshape trade with countries buying Russian energy, adding uncertainty for exporters from India to China just as diplomacy intensifies.

A claimed US security role over Greenland would mark a shift in transatlantic and Arctic arrangements, though the precise terms of any Danish agreement remain to be clarified.

OpenAI's projected $280bn cash burn crystallises investor questions about the sustainability of AI spending, while the Gemini breakout and Anthropic's safety investment show that governance risks are becoming material for the largest technology firms.

What to watch

The Sunday talks involving Bessent, Greer and He Lifeng, and whether they yield movement on LNG tariffs or rare earths before Xi's arrival.

Confirmation and detail of the US-Denmark Greenland arrangement, which Copenhagen has yet to spell out publicly in the sources available.

Any appeal by the Trump administration of the 1st US Circuit ruling blocking third-country deportations, which could reach the Supreme Court.
