Belgrade allows UN Kosovo mission
Refugees continue to arrive at border camps
Yugoslavia is to allow a United Nations humanitarian mission to visit Kosovo.
Conditions in the Serbian province remain a mystery, but refugees have told relief agencies that the security forces have been destroying food stocks to make them leave.
Mr De Mello told a news conference that Vladislav Jovanovic had confirmed "his government would facilitate the conduct of the mission".
An advance team is preparing to leave for Belgrade. It will include representatives of the UN Children's Fund, the UN High Commissioner for Refugees and the UN's Office for the Co-ordination of Humanitarian Affairs.
The mission is expected to report to the secretary general by 13 May - the day Mr Annan has fixed for a meeting of all UN agencies involved in the Kosovo refugee crisis.
UN relief agencies have not been in Yugoslavia since the Nato air strikes began on 24 March.
It is not known how many refugees are in Kosovo; neither journalists nor relief agencies have operated there since the Nato air campaign began in March.
Mr Annan said on Tuesday that he planned to send a UN mission to "assess the situation on the ground, determine the magnitude of the problem and what we need to do to prepare the ground for the refugees to go back to Kosovo".
He also said he had not asked for a pause or lull in the Nato bombing while the team was in the country but indicated some arrangements might be made.
The International Committee of the Red Cross has already been granted permission to resume operations in Kosovo.
Cornelio Sommaruga, President of the ICRC, visited Yugoslav President Slobodan Milosevic to get permission to work in Kosovo.
After a meeting on 27 April Mr Sommaruga said President Milosevic was "very positive" about the ICRC's return but the two sides still had to agree on how the Red Cross would operate there.
