UN Secretary-General Ban Ki-Moon will visit Burma this week to discuss what can be done to speed up the troubled aid operation for victims of Cyclone Nargis.
Ban Ki-Moon expected in Burma this weekThe UN boss is expected to visit the country on Wednesday or Thursday.
He has so far been unable to contact the leader of the country's military junta, Than Shwe.
State television showed Than Shwe making his first visit to relief camps on the outskirts of Yangon on Sunday.
Meanwhile, the UN's top disaster relief chief has landed in Burma to urge the country to opens its doors to foreign aid.
UN Undersecretary-General for Humanitarian Affairs John Holmes was received at the airport by Deputy Foreign Minister Kyaw Thu.
It is unclear whether he will meet leading members of the junta.
His spokeswoman Amanda Pitt told Sky News Mr Holmes would "help the government understand what's available to them" in the wake of the cyclone .
"The response to a disaster of this magnitude is beyond any one country," she said.
Mr Holmes will also meet other agencies working in Burma to review and coordinate the relief operation.
Still waiting: thousands need helpThe country's military government has severely restricted distribution of aid supplies, leaving many of the disaster's estimated 2.5 million survivors in dire need of food, water and shelter.
UK charity Save the Children warns that thousands of children could die in coming weeks unless more aid is let in.
The charity also warned that time was running out to start planting for the coming rice harvest.
An estimated 30,000 children under the age of five in the affected region were already acutely malnourished prior to the disaster, according to research by the charity.
A Sky News reporter in the Irrawaddy Delta said there was little evidence of government aid being distributed.
Gordon Brown has accused the regime of "inhuman" treatment of survivors.
The Prime Minister said the natural disaster was becoming a "man-made catastrophe" because of the ruling junta's failings.
Burmese authorities put the death toll from the cyclone at 78,000 with a further 56,000 people missing.
