RUMANIA'S INDEPENDENT LINE AMONG THE COMMUNIST-BLOC OF COUNTRIES WAS REFORTIFIED AT THIS WEEK'S CONGRESS OF THE COUNTRY'S COMMUNIST PARTY.

BY THE CLOSING SESSION ON THURSDAY (NOVEMBER 28), THE POSITION OF PRESIDENT NICOLAE CEAUSESCU HAD ALSO BEEN GREATLY STRENGTHENED -- EVEN THOUGH HE EARLIER TURNED DOWN A CONGRESS PROPOSAL TO MAKE HIM RUMANIA'S COMMUNIST LEADER FOR LIFE.

NEVERTHELESS, THE CONGRESS DID ELECT MR. CEAUSESCU TO A NEW FIVE-YEAR TERM AS PARTY SECRETARY-GENERAL. AND FIVE NEW MEMBERS ELECTED TO THE POLICY-MAKING EXECUTIVE POLITICAL COMMITTEE ARE ALL CLOSE AIDES OF THE 56-YEAR-OLD LEADER.

IN HIS CLOSING SPEECH TO THE 2,400 DELEGATES, MR. CEAUSESCU PLEDGED THAT HE WOULD STRICTLY MAINTAIN HIS INDEPENDENT FOREIGN POLICY, WHICH HAS OFTEN FOUND HIM AT ODDS WITH THE SOVIET UNION. AND THE CONGRESS APPROVED A NEW CHARTER BACKING HIS POLICY, WHICH WARNED RUMANIA'S COMMUNIST ALLIES THAT "SOLIDARITY IS INCOMPATIBLE WITH INTERFERENCE IN INTERNAL AFFAIRS."
