The leader of the Afghan resistance alliance is asking for U.S. money to help refugees and to rehabilitate his war-torn country in talks Tuesday with State Department officials.

There was no advance price tag as Burhanuddin Rabbani outlined his plans for Afghanistan's future. At a session Monday with Undersecretary of State Michael H. Armacost he gave an initial description of the elections he said he wants to hold in January to select a new government in Kabul.A U.S. official, who spoke on condition of anonymity, said Rabbani did not ask for additional American military aid to carry out the guerrillas' fight against pro-Moscow government forces.

"They didn't come in pressing for more guns," the official said. "They are confident of their ability to see this war to its end."

Although the level of U.S. military support remains secret, the rebels are believed to have received several hundred million dollars in recent years. Much of the aid, including shoulder-fired Stinger missiles, is channeled through Pakistan.

Rabbani, who sees President Reagan and Secretary of State George P. Shultz on Wednesday, is the leader of the Islamic Society guerrilla group and of the main rebel alliance. He had talks scheduled Tuesday with Assistant Secretary of State Richard Williamson, who coordinates humanitarian aid to the rebels, and with the Agency for International Development.

"It was a very cordial meeting," a U.S. official reported after Monday's session. "There was a restating of our support for the Mujahedeen. Both sides gave their assessment of the issues."

The official, who spoke on condition of anonymity, said Rabbani and Armacost just "touched on" the guerrilla leader's plan, and that it would receive more extensive consideration later in the week.

The Reagan administration already has registered its general support for a political settlement, provided it involves self-determination for the Afghan people.
