China's New Ambassador Aims to Improve Relations with U.S.

Xie Feng, China's new ambassador to the US, arrived in Washington to potentially warm ties between the two countries, but warned of "serious difficulties and challenges" in the relationship. Despite recent high-level talks, there are still obstacles to overcome, including concerns over the ongoing FBI investigation into a Chinese balloon shot down by the US and accusations of China operating illegal police stations in New York. Meanwhile, China is seeking closer ties with Europe, but the US is urging its allies to choose sides.
