Reagan Pledges to Offer Soviets New Arms Plan

President Reagan today began a two-day visit to Spain amid massive anti-American protests and pledged to make a new arms control proposal to the Soviet Union before ending his European trip later this week.

Before leaving Germany, White House spokesman Larry Speakes said Reagan’s speech to the European Parliament in Strasbourg, France, on Wednesday will contain “very important . . . definite proposals regarding the Soviets,” including open borders from Moscow to Lisbon.

In broad terms, he said, the speech will include these proposals:

--A military-to-military communication between the United States and the Soviet Union to prevent such incidents as the Sept. 1, 1983, shooting down of Korean Air Lines flight No. 007.

--Open borders, so people “could travel from Lisbon to Moscow without any problems.”

--A further response to the Soviet pledge not to be first to use nuclear weapons. The Soviets dismissed as inadequate Reagan’s initial response last year, when he expressed a willingness to discuss the subject.

Greeted by King and Queen

Later in Madrid, when Reagan was asked whether he was going to propose a new arms initiative in his speech, he would only say: “No, I’m going to be discussing what we’re trying to achieve in arms reduction.”

Leaving behind a difficult economic summit and controversy over his visit to a Nazi grave site in West Germany, Reagan and his wife, Nancy, stepped off Air Force One into brilliant sunlight to be greeted by King Juan Carlos and Queen Sofia.

The day before, 200,000 anti-American demonstrators marched in Madrid and other Spanish cities to protest the visit. They urged closing four military bases leased from Spain under a 1953 agreement, and pulling Spain out of the North Atlantic Treaty Organization.

At the airport, the two couples reviewed troops, while, out of their sight and earshot, about 30 Nicaraguans protested the U.S. trade embargo imposed on their country, another major issue on Reagan’s agenda here.

Pots-and-Pans Protest

With the government refusing demonstration permits on weekdays, protesters urged Madrid residents to shut off their lights and bang pots and pans for 10 minutes during Reagan’s first evening in Spain.

From the airport, the Reagans left for their residence during this two-day stay, El Pardo Palace. The 63-room estate nine miles northwest of Madrid served as home and headquarters to Spain’s authoritarian ruler Gen. Francisco Franco from 1939 to his death in 1975.
