BEIJING (AFP) - China’s Vice President Xi Jinping made his first public appearance in two weeks on Saturday following swirling speculation about the whereabouts of Beijing’s leader-in-waiting. Xi looked relaxed in television pictures which showed him visiting a university - his first public outing since intense speculation about his health surfaced after he cancelled meetings with four foreign dignitaries this month, including visiting US Secretary of State Hillary Clinton. He was accompanied by a trio of top party bosses for his visit to China Agricultural University in Beijing for “activities marking this year’s National Science Popularisation Day”, state run Xinhua said.
