The first US military aid flight to Burma landed in Rangoon today, but emergency supplies remained at a trickle for 1.5 million people facing hunger and disease in the cyclone-ravaged Irrawaddy delta.
The C-130 military transport plane left Thailand's U-Tapao air base carrying water, mosquito nets and blankets to the military-ruled country.
The junta's navy Commander-in-Chief Soe Thein greeted the US supplies, which were accompanied by Admiral Timothy Keating, head of the US Pacific Command, and Henrietta Fore, administrator of the US Agency for International Development.
In New York, UN Secretary-General Ban Ki-moon said he was immensely frustrated at the unacceptably slow delivery of aid in general.
He said he had been unable to contact Burma's senior general, Than Shwe, despite repeated attempts.
US President George W Bush denounced Burma's military rulers over their response to the devastating cyclone.
He said that the world ought to be angry and condemn the junta.
A US AID administrator said permission has been given for two more planes to land tomorrow, but there was no breakthrough on the important issue of letting foreign helicopters and boats ferry supplies into the delta.
The US is increasing its humanitarian aid to $16m, from $3.5m. Delivery of the aid shipment was broadcast on Burma state television.

Experts say much more aid is needed as help has reached less than one-third of those in need.
The official death toll has risen to over 28,000, while around 33,000 people are listed as missing.
Aid agencies estimate that 100,000 people have died.
The Irish Red Cross has announced it pledged €50,000 to fund tents, tarpaulins and other types of emergency shelter in Burma.
