WASHINGTON, April 6—Nations around the world appeared today to be deliberately withholding comment on the Pakistani Government's military actions in East Pakistan for fear of inflaming the situation.

The United States, which had 750 citizens in East Pakistan, has held comment to a minimum. At least 307 United States citizens were reported today to have been flown by Pakistan International Airlines away from the strife‐tom eastern part of the country to Karachi. Of these; 184 were private, citizens and 123 Government officials and their dependents.

President Nikolal V.Podgorny of the Soviet Union called in a message to President Agha Mohammad Yahya Khan of Pakistan last week for a “peaceful solution.” He warned that reports of “extreme” measures by Pakistan's armed forces against East Pakistanis had caused “great alarm” in the Soviet Union.

On the other hand Communist China, which has been furnishing arms to Pakistan since the Indian Pakistan war in 1965 led to a United States arms embargo, appeared to be siding with Pakistan, although it has withheld comment.

India, while critical of Pakistan's actions, was officially restrained, And Britain, leader of the Commonwealth of which both Pakistan and India are members, was maintaining virtually total silence on what Sir Alec Dougles‐Home, the British Foreign Secretary, has called an “internal matter.”

France, West Germany, Yugoslavia, Japan and Nepal have been hurriedly evacuating their citizens from East Pakistan, but otherwise these countries were silent. So far, United States analysts have noted, no country has urged the independence of East Pakistan or has moved to promote such a course.

The Pakistani Government, which refused the United States permission last week to evacuate its citizens by military air planes to Thailand, has promised to send one civilian airliner each day to fly all Americans who wish to leave from Dacca to Karachi. It has been estimated here that this may involve 700 to 750 persons.

Until the airlift evacuation is completed within the next two or three days, however, the United States is unlikely to express more than muted “concern” over the reported, use of United States arms by the Pakistani Army in suppressing the independence movement in East Pakistan.

Fear of Reprisals

Fear of reprisals, against American citizens and United State's property or the total Shutdown of United States communications from the consulate general is Dacca is reliably believed to have been behind the extreme moderation on all comment from Government circles here imposed by the White House since violence in East Pakistan erupted last month.

The United States, for instance, has reported its “concern” to the Pakistan Government over the expulsion of 37 American and other foreign correspondents from Dacca and the seizure of their notebooks, cameras and other effects.

The United States also expressed “concern” last Friday over “reported loss of life, damage and hardship” to the East Pakistan people.

Yesterday Charles W. Bray 3d, the State Department spokesman, said that the United States hoped for a “peaceful settlement” of the dispute.

Simultaneously, the United States offered “sympathetic consideration” to joining an international humanitarian relief effort, provided it wag requested by Pakistan and, was “in line” with similar proposals by Secretary General Thant of the United Nations.
