Secretary of State Alexander M. Haig Jr., in an interview published yesterday, cast doubt on the recent practive of regular sami-annual summit meetings of the free world's leaders.

Haig, in an interview with the London Sunday Times, said meetings of the top leaders should be "used sparingly." He also said that summits are "a very special vehicle in diplomacy that should be reserved only for the most exceptionally significant of issues."

The secretary of state, however, expressed the hope of establishing increasingly close relations and exchanges of intelligence with the European allies, if the Central Intelligence Agency can plug its news leaks.

"First and foremost, we have got to do a better job in developing and sharing common perceptions," Haig added. "That means sharing our intelligence, agreeing on the hard facts and recognizing that everybody can contribute to this process.

"But we can only expect our European partners to participate in such exchanges if they can be protected against immediate revelations on the front pages of American newspapers," he said. "We, therefore, have to tighten up our international channels of communications."

Haig said newly appointed CIA Director William J. Casey "is very much dedicated to this."

Haig said the new administration is keeping its options open on nuclear disarmament and the SALT II pact.

"It has been my experience that achieving arms control is never the product of rhetoric or idealistic hopes," Haig said. "It is always the product of pragmatic reality."

Haig said Soviet behavior in world troublespots and what he called "technical flaws" in SALT II would affect how President Reagan decides to deal with arms control.

"We are looking at these problems and I don't know yet how we will proceed from here -- whether to develop a whole new treaty, whether to put fixes into the existing treaty or whether to do it by amendments," he said.
