China's Defense Chief and U.S. Secretary Clash at Singapore Summit.

China's new defense minister, Li Shangfu, made his first international appearance at the annual Shangri-La Dialogue summit in Singapore, where he delivered a speech full of thinly-veiled barbs at the US, calling on its competitor to "mind your own business" after two close encounters between the country's militaries. The US and China are competing for influence in the Asia Pacific, with both boosting their military activity and arms build-up in the region. Meanwhile, political heavy-hitters from the European Union and Ukraine also traveled to Singapore to rally support for Ukraine in its fight to expel Russian troops from its territory.
