Top Vietnam leader misses meetings amid health concerns

But he is not scheduled to meet Indonesia's President Joko Widodo during a state visit on Friday, according to draft agendas from Vietnam's foreign ministry and Indonesia's presidential office.

Trong was also not on the list of Vietnamese leaders who received Laos' Prime Minister Sonexay Siphandone last weekend.

He has not been seen in public since December 26, when he met in Hanoi the head of the Japanese Communist party Kazuo Shii.

Vietnam's foreign ministry did not immediately reply to a request for comment about Trong's health.
