KGB chief Vladimir Kryuchkov repeated dark warnings Saturday that the CIA and other foreign forces are trying to "impose doubtful ideas and plans" that heighten the crisis in the Soviet Union.

The secret police chief, speaking during a debate at the fourth Congress of People's Deputies on proposed new powers for President Mikhail Gorbachev, said unless "resolute actions to establish law and order" are taken, the country will slide further into chaos.Kryuchkov's speech on the sixth day of the Congress, spiced with Cold War rhetoric, appeared to be part of a conservative counterattack against charges that hard-liners were gaining too much influence in the government.

"The KGB is sure that if the situation in our country develops in the same direction in the future, we shall not avoid more serious and difficult social and political upheavals," Kryuchkov told the Congress.

He repeated charges first voiced in a television address Dec. 11 that anti-Soviet foreign intelligence services were working in new ways and had even escalated their activity after the end of the Cold War.

Kryuchkov said unspecified outside forces "are trying to exert pressure on the Soviet Union and to impose doubtful ideas and plans to pull the country out of the difficult situation."

"Despite a thaw in international relations, a substantial increase was registered in the activities of some Western secret services to collect information about the political situation in the Soviet Union," Kryuchkov said.

He added that the CIA "does not intend to stop using the Radio Liberty station and anti-Soviet organizations on its payroll" and charged the U.S. intelligence agency was also funding a group called the People's Labor Union that "has assumed the role of the chief catalyst of anti-socialist forces."

Kryuchkov acknowledged "the main sources of our troubles are inside the country," but he added nationalist forces in the Ukraine and the Baltic republics were being assisted by emigres.

He blamed many of the shortages in the country on the "shadow economy" that has operated more freely under perestroika.
