China's Vice President Xi Jinping
Chinese authorities and media remained silent on the whereabouts of Vice President Xi Jinping on Wednesday, sparking rumours and raising questions over why Beijing is not being more forthcoming on the health of its president-in-waiting.
Xi has skipped meetings with visiting leaders and senior officials over the past week, including U.S. Secretary of State Hillary Clinton, because of what sources told Reuters was a possible back injury suffered while swimming.
Xi has not been seen in public since September 1 but Chinese officials have refused to give any explanation for his absence from the public stage, giving rise to bizarre speculation on the country's Internet rumour mill.
Xi failed to appear on state television's evening broadcast on Wednesday, which featured almost every other member of the nine-man Politburo Standing Committee, China's top political body.
Among various theories being floated, the 59-year-old Xi has had a stroke or heart attack or was the target of an assassination attempt.
Foreign Ministry spokesman, Hong Lei, asked on Wednesday for the third consecutive day about Xi's health, again declined to respond. "I don't have any information about this to announce," he said.
The ministry, for the most part the only government department that regularly takes question from foreign reporters, has repeatedly refused to comment on Xi's status and whereabouts.
"Something serious must have happened, because they would have put him on national TV right away had there been no serious physical problem," said Minxin Pei, professor of government at Claremont McKenna College in California.
"I rule out political foul play, that he is in some kind of serious political trouble. It's simply unimaginable. He gave a speech on September 1, and that's after Beidaihe - if he were in political trouble, he wouldn't have given that speech."
Beidaihe is the seaside summer retreat of senior Communist Party leaders, who meet there every August to hammer out policies for the coming year. This year the talks were likely to have focused on the new party leadership to be unveiled at the party congress expected to be held in October.
With the congress held only once every five years and its top leaders being replaced only every decade, it is China's most important political event. The fact that its timing has not yet been announced has fuelled speculation about discord within the party.
One of the more bizarre rumours - first floated then retracted by overseas Chinese website Boxun -- was that Xi and He Guoqiang, another standing committee member, were targets of separate assassination attempts by staged car crashes.
He Guoqiang made his first public appearance since late August on the evening news on Wednesday, visiting a newspaper publisher in apparent good health.
