The new US ambassador to China Gary Locke made his first public appearance this weekend in Beijing, using the opportunity to assure China that its investment in the US dollar is safe. With headlines in Chinese state media like “Locke to rebuild US reputation” and “New US ambassador faces a tough job“, the tone in Beijing seems at the very least welcoming, if not optimistic over the arrival of the former US Secretary of Commerce. After burning up the Chinese internets last weekend because he buys his own coffee and carries his own backpack, Locke was asked whether he plans to use social media to speak directly with Chinese citizens, and responded “We look forward to using all forms of communications, including blogging and the electronic media.” In the mean time, you can follow him on Twitter at @AmbLocke. Surprisingly, we still can’t find a verified account for him on Weibo! But you can follow the U.S. Embassy in Beijing here.
