Zardari was to meet the leader of China in Beijing on Wednesday, as he reaches out to a close ally for increased investment to aid his country's ailing economy. A possible deal between the countries on civil nuclear power is also highly anticipated. Such an agreement would serve as a counterpoint to a recent deal between India and the United States that cleared the way for American businesses to sell nuclear fuel and technology to India for use in its civilian programs.(AP Photo/ Elizabeth Dalziel)
