From the Associated Press:

Citing national security risks, President Barack Obama on Friday blocked a Chinese company from owning four wind farm projects in northern Oregon near a Navy base where the U.S. military flies unmanned drones and electronic-warfare planes on training missions.

It was the first time in 22 years that a U.S. president blocked such a foreign business deal. …

The military has acknowledged that it used the Oregon Naval facility to test unmanned drones and the EA-18G “Growler.” The electronic warfare aircraft accompanies U.S. fighter bombers on missions and protectively jams enemy radar, destroying them with missiles along the way.

At the Oregon site, the planes fly as low as 200 feet and nearly 300 miles per hour. …

China’s trade advantage over the U.S. has emerged as a key issue in the final weeks of the presidential campaign. Romney accuses Obama of failing to stand up to Beijing, while the president criticizes the GOP nominee for investing part of his personal fortune in China and outsourcing jobs there while he ran the private equity firm Bain Capital.
