"The UK summit is referenced in the executive order. But it's mentioned under the heading of'advancing American leadership abroad' - indicating that the US very clearly knows that it is the big player here alongside China but more precisely, it is the US companies that are really driving forward," he said.

The United States has announced a new $1.2bn military aid package for Ukraine that will include air defence systems, conventional artillery and counter-drone ammunition, satellite imagery services, as well as funding for military training. In the package announced on Tuesday, Ukraine will also receive technology to allow the integration of Western air defence launchers, missiles and radars with Ukraine's native air defence systems. "The Russians have launched waves of missiles into Ukraine, whose military has been adept at knocking them down. The package also contains ammunition to shoot down unmanned aerial systems," the US Department of Defense said in a statement. Ukrainian cities have come under renewed aerial attacks in the past week with scores of Russian missiles and drones targeting the capital Kyiv and other key cities.

The US government is announcing $1 billion in new funding for multidisciplinary AI and quantum computing research hubs today, according to multiple reports. A total of 12 hubs will be funded, each embedded within different agencies of the federal government. The investment is part of a slow push from the White House to fund emerging technologies. Many policy advisors have worried that America is falling behind in AI and quantum research compared to rivals like China, and warn that these technologies are instrumental not only for economic development but also national security. It's extremely difficult to make a fair comparison of US and Chinese spend on technology like AI as funding and research in this area is diffuse.
