Donald Tsang Yam-kuen is set to meet top state leaders for the first time since becoming acting chief executive, when he attends the annual Boao Forum for Asia in Hainan this month. He is expected to meet either President Hu Jintao or Premier Wen Jiabao during the event from April 22 to 24 - just a couple of days before a National People's Congress Standing Committee meeting during which it is likely to interpret Basic Law clauses on how long the next chief executive should serve. The Boao Forum confirmed Mr Tsang would attend in his capacity as acting chief executive. His office did not comment last night. City University political analyst Ivan Choy Chi-keung said leaders would likely use the occasion to openly lend support to Mr Tsang. 'The meeting will be a gesture to show Beijing's support to the [Hong Kong] government and especially Donald Tsang at a time when the NPC is expected to interpret the Basic Law,' he said.
