In the first Soviet press report on the upcoming U.S.-Soviet summit since the proposal of a 50 percent cut in arms brought to the White House Friday by Foreign Minister Eduard Shevardnazde, an article in the Soviet Communist Party newspaper Pravda today accused the United States of taking "an intransigent, defiant stance" in its preparations for the November meeting.

President Reagan and his aides "make it clear that they will stick to the old position which is far from being a realistic one," wrote Pravda analyst Yuri Zhukov. "It is high time they in Washington realized that Moscow has never played at give-away, and that it does not and will not do so."

The slightly subdued tone of the Pravda article contrasted with the sharply polemical language in many recent Soviet press reports about the summit. "Today is not too late to busy oneself with these affairs," it said, referring to concrete preparations for the summit.

Echoing the point, Soviet analyst Boris Kalyagin said in a news program today, "There is still some time before the summit meeting. There are still possibilities to make it constructive and useful."

Neither in the Pravda article nor elsewhere in the Soviet press have reports appeared on the bilateral 50 percent reduction in nuclear weapons proposed by Shevardnadze to Reagan as a trade-off for the United States scrapping its Strategic Defense Initiative. Pravda related the bare facts about the Reagan-Shevardnadze meeting in a page 4 article Saturday.

Soviet officials have suggested that the proposals will be presented at the U.S.-Soviet arms talks in Geneva, which recently started their third round.

Soviet officials here said before the Reagan-Shevardnadze meeting that the Soviet Union would table its arms proposals in Geneva if they received a positive response from U.S. officials.

The Friday meeting, Reagan's second with a high-level Soviet official since his election in November 1980, is viewed in diplomatic circles here as an important preparatory step to the summit, scheduled to take place in Geneva Nov. 19-20.

The article in today's Pravda said that the "tangible political initiatives" the Soviet Union has taken on arms control "are in everyone's view."

"But as for the U.S. side, nothing is heard from across the ocean except the mounting anti-Soviet propaganda," the article said.

Headlined "Questions That Remain Without an Answer," the Zhukov article referred to various questions on the summit posed by journalists to White House spokesman Larry Speakes that it charged have not been adequately answered. Among the seven questions that Zhukov said had been raised in a recent White House briefing were whether Reagan agrees with Soviet leader Mikhail Gorbachev that U.S.-Soviet relations are "deteriorating," and whether the United States views the summit as merely a chance to get acquainted.
