Wen Jiabao was appointed to a second five-year term as premier on 16 March 2008, leading efforts to cool soaring inflation and showcase the country to the world at the 2008 Summer Olympics. He received fewer votes in favour than he did in 2003, a sign that the premiership can create enemies, even in the mere formalities of China's electoral system. Wen faced grave economic challenges as the world became increasingly affected by the U.S. economic crisis. Social stability and regional activism in China's restive hinterland regions also dominated Wen's policy agenda. On 18 March 2008, during the press conference after the 2008 National People's Congress, Wen toed the government line in blaming supporters of the Dalai Lama for violence in Tibet, and said Chinese security forces exercised restraint in confronting rioting and unrest in the streets of Lhasa. Wen acted as the spokesman of the Chinese government during the 2008 unrest in Tibet and refused to negotiate with the Dalai Lama and his followers, unless they chose to "give up all separatist activities." On 12 November 2010, during the 2010 Asian Games opening ceremony in Guangzhou, Wen became the first non-head of state to open the Asian Games.
