NEW DELHI, Oct. 16 (Reuters)—President Tito of Yugoslavia arrived here today for an official visit of several days, during which he will discuss international problems with Prime Minister Indira Gandhi and the Indian‐Soviet treaty signed In August.

The Indian Defense Ministry said today that Pakistan was building up her forces in the border areas in East and West Pakistan but that India had taken adequate steps to counter any Pakistani plans to at tack.

The treaty of peace, friend ship and cooperation signed with the Soviet Union is expected to be a major subject of discussion during the visit. Mrs. Gandhi and Mr. Tito are regarded as advocates of non alignment.

Yugoslav sources said that the treaty had marked a new step for a nonaligned nation but added that their Government had accepted Indian statements that it would not affect New Delhi's policies. The Yugoslavs made it clear, however, that Yugoslavia had no intention of signing a similar pact.

is 5th Visit

On the East Pakistani issue, Yugoslavia has supported India's demand for a political solution to the secessionist demands by the Bengalis.

The President, accompanied by his wife, is on his fifth visit to India since 1954. He has not met Mrs. Gandhi since the conference of nonaligned nations in Lusaka, Zambia, last year.

Mr. Tito traveled from Iran, where he had attended ceremonies commemorating the 2,500 anniversary of the Persian Empire.

The Indian Defense Ministry spokesman's comments on Pakistani troop build‐ups came after all major New Delhi news papers reported today that Pakistani troops, supported by heavy equipment, were massing along the frontier areas.

Mrs. Gandhi discussed the latest situation with colleagues of the Political Affairs Committee, the inner Cabinet, after a full Cabinet session.

Press reports of Pakistani war preparations have been given steadily greater prominence recently, but Foreign Ministry officials say they are puzzled by the Pakistani moves.

An attack on India would be suicidal, they say, but they believe the Pakistani military, regime is showing signs of strain and division because of the civil war in East Pakistan. India says some nine million refugees have fled into India.

The Indian officials do not believe the situation has worsened markedly although the danger of war undoubtedly exists.
