WASHINGTON, Dec. 14—The White House is letting it be known that President Nixon will reconsider his planned trip to Moscow unless the Soviet Union uses its influence with India to bring about cease‐fire in her war with Pakistan.

This Administration view was given in a background briefing to a small group of reporters today by Henry A. Kissinger, the President's national security adviser. Mr. Kissinger said that the President, disturbed by Soviet vetoes of cease‐fire resolutions In the United Nations Security Council, believes that Moscow is seeking to humiliate Peking by demonstrating that China—a supporter of Pakistan — cannot prevent Pakistan's defeat.

A pool report of the briefing was later made available to other correspondents, and The Washington Post first publicly disclosed that Mr. Kissinger had conducted the background session.

Meanwhile the Indian Ambassador to Washington, L. K. Jha, charged this afternoon that Government had information from “a reliable source” that the United States nuclear-equipped and powered carrier Enterprise was sailing toward East Pakistan with contingency orders that included the evacuation of Pakistani personnel bottled up by the Indians in Dacca.

Ambassador Jha said that he had raised the matter with Joseph J. Sisco, Assistant Secretary of State of Near Eastern and South Asian Affairs, this afternoon and had no received a categorical denial.

He declined to reveal his sources but said that such plan would be regarded in New Delhi as “a very serious matter.”

Officially, neither the State Department nor the Pentagon would comment on the charge. But Administration officials said privately that the Enterprise, four destroyers and an amphibious ship carrying two dozen helicopters were under orders to sail from Singapore into the Indian Ocean. They said that no orders had yet been given to proceed from there.

Trip Scheduled for May

The White House intention to link the President's Moscow trip next May to Soviet willingness to promote a cease‐fire between India and Pakistan was the latest indication that the White House regards India as the aggressor in the war with Pakistan and that Mr. Nixon is disturbed by the lack of evidence that Moscow wants its new allies, the Indians, honor a United Nations General Assembly call for a cease‐fire.

Mr. Kissinger said that the President regarded the Russians as capable of restraining the Indians but believed that they did not do so within the next few days he would have to reassess the entire relationship between Washington and Moscow.

Unless the Russians indicate quickly that they will seek restrain India's military thrust into East Pakistan and her combat efforts along the border with West Pakistan, Mr. Nixon will seriously consider holding off attempts to reach a detenté with Moscow, Mr. Kissinger said.

He told reporters the United States was still working on variety of diplomatic fronts bring the war to a close. complained, as officials at State Department had yester. day, that the Soviet Union had not played a constructive role —“to put it mildly.”

He said that the White House was trying to prevent not only the dismemberment of Pakistan but any military threat to West Pakistan.

Asked if Pakistan could he viable state should the centre Government lose control East Pakistan, as now seem likely, Mr. Kissinger said that the United States view as the Pakistan could survive if then were certain unspecified changes in the eastern region.

The President had tried to win France's support for the cease‐fire resolutions at the United Nations. The Pompidou Government has abstained, however, from voting on the issue.

An official familiar with the talks between Presidents Nixon and Pompidou said that the French apparently decided there was nothing to be gained in taking a stand on the ceasefire issue because the resolutions were sure to be vetoed by the Soviet Union in the Security Council.

Previous Comments Noted

At a briefing for newsmen last week, Mr. Kissinger said that the White House felt the Soviet Union had not used its influence on, he Indians. The briefing was provided on the condition that Mr. Kissinger not be publicly identified. But his identity was subsequently made public by Senator Barry Goldwater of Arizona.

The President's increasing dissatisfaction with Moscow—as it was made known here today—thus represented a lowkey attempt to send a signal to the Soviet Union without directly attributing it to Mr. Nixon himself.

Meanwhile, the American carrier Enterprise rendezvoused with the five other Navy ships yesterday off Singapore. It would take the convoy three to four days to travel the 1,600 nautical miles to East Pakistan.

Ambassador Jha said that the Indian Government and the Bangla Desh (Bengal Nation) insurgents in East Pakistan had insured the safety of all foreign nationals in East Pakistan and that all Americans who wished to leave had already done so.

Ziegler Comments

Ronald L. Ziegler, the White House press secretary, first learned of the report of the President's attitude toward Moscow when he arrived in Washington several hours after Mr. Nixon and his official party returned from the Azores, where the President conferred with President Pompidon of France.

“The United States is not considering canceling the U.S. Soviet summit and no U.S. Government official intended to suggest this,” Mr. Ziegler insisted.

Despite the clear impressions received by those who heard Mr. Kissinger express the White House viewpoint, Mr. Ziegler said that the accounts were “highly speculative and taken out of context.”

According to Mr. Ziegler, Mr. Kissinger was discussing a “highly hypothetical situation.”

“If the Soviets continued to support Indian military action and the Indians should move into West Pakistan, this could very well affect future relations with the Soviet Union,” the press secretary said. “But we have no reason to suspect this will occur. We have every expectation the fighting will stop in South Asia.”
