WASHINGTON, D.C., Oct. 29--"There is little chance that China will be permitted to enter the United Nations in the immediate future," a high government official said yesterday during the final session of the National Foreign Policy Conference for Editors and Broadcasters.

Communist China, the official explained, has stated that it will enter the U.N. only if the following conditions are met: the U.N. must apologize for blaming the Korean war on Chinese and North Korean aggression, it must expel all "American-Imperialist-Iackey" nations, and it must return Taiwan to the Communist Chinese.

Speaking about the possibility of a U.N. solution to the Vietnamese war, a different official had argued previously that "the U.N. will patrol a war but is not likely to wage war." He also added that a full scale debate in the U.N. Security Council would only embarrass the Russians politically and force them into an even less flexible position on Vietnam. With no solution in sight, the official concluded, "a debate on this issue would only aggravate the current situation."

The Chinese also don't want to negotiate over Vietnam, the official vowed. "They simply want to disrupt the United Nation's organization," he said. The Chinese Minister of Defense, the official continued, has written in his Theory of Revolutions will strangle capitalist nations by controlling the under-developed nations. Clearly, the Chinese are more interested in exporting Communism than in joining a responsible world community, the official said.

Latin America

The recent increase in Castelo Branco's dictatorial power will provoke no immediate political or economic reprisals by the United States, another government spokesman said during a round table discussion at the State Department. The O.A.S. conference is still temporarily scheduled to take place in Brazil on Nov. 17, and will presumably deal with the problem of economic integration in Latin America and the controversial issue of intervention, he reaffirmed.

One official reported that the Selden Proposal (passed by the House to justify multi-lateral intervention in South America wherever there is evidence of Communist subversion) had brought more complaints from the Latins than the Dominican Republic crisis.

The press conference, which convenes twice annually at the State Department, came to a close yesterday at noon. Rome 16 university newspapers were represented at the conference for the first time.

No comment made during the conference could be attributed to an individual or his agency, government official said
