SINGAPORE -- As car crash interviews go, Bruce Aylward's was excruciating and revealing in equal measure. In late March, Alyward, a Canadian epidemiologist and adviser to the World Health Organization, was asked by Radio Television Hong Kong reporter Yvonne Tong whether Taiwan would continue to be denied WHO membership, given longstanding objections from China. At first he stalled, claiming not to be able to hear the question. Then his connection went down. Then Aylward returned to the call and declined to answer at all.
