Here are the highlights of the American response to the Soviet invasion of Afghanistan as outlined by President Carter in his television address last night or as described privately by Carter administration officials:

Blocking delivery of 17 milliom metric tons of U.S. grain ordered by the Soviet Union to help build up its livestock herds and provide more meat for Soviet consumers.

Providing military equipment, food and other aid to Pakistan to "help defend its independence" against threats from neighboring Afghanistan and standing ready to "help other nations in the region in similar ways."

Instructing Defense Secretary Harold Brown, who left for China yesterday, to discuss with Chinese leaders cooperative U.S.-Chinese measures to bolster Pakistan.

Halting immediately the sale of high technology and strategic items such as computers and sophisticated machinery to the Soviets.

Threatening to withdraw from the 1980 Olympic Games in Moscow next summer if the Soviet Union, "through continued aggressive actions," poses a danger to American athletes and spectators.

Delaying the opening of new American and Soviet consulates -- a move that most immediately will affect scheduled new facilities in New York and Kiev -- and deferring most of the cultural and economic exchanges being considered by the two countries.

Cutting back sharply the fishing privileges enjoyed by the Soviets in U.S. waters, from a scheduled take of 350,000 tons in 1980 to 75,000 tons -- a move U.S. officials say will cost the Soviets $55 million to $60 million.

Reiterating that Senate consideration of the strategic arms limitation treaty (SALT II) will be delayed until the president and Congress "can assess Soviet actions and intentions."
