The proposals of Secretary General Kurt Waldheim for a cease-fire and U.S.-supervised elections in Namibia (Southwest Africa) with criticism from the South African government.

Judging from remarks of the Prime Minister Pieter W. Botha in Parliament Monday, South Africa is not pleased with certain aspects of the proposals. Botha made his statement before he received the final text Monday night but after being informed of the general content.

"It has become clear that a serious situation has arisen in connection with the implementation of the settlement plan," Botha said of the Western-drafted proposals that would lead Namibia, now administered by Pretoria, to independence under black majority rule by the end of the year.

Botha objected to the absence of any U.N. monitoring of bases in neighboring Angola belonging to the black nationalist guerrilla group, the Southwest Africa Peoples' Organization (SWAPO), which has been fighting to bring down South African rule in the territory. Instead the United Nations calls for the camps to be monitored by SWAPO's allies, Angolan troops.

The prime minister also denounced a clause that would allow SWAPO guerrillas inside Southwest Africa at the time of the cease-fire in mid-March to remain there at established bases. The guerrillas have no bases there at present.

Waldheim has requested both South Africa and the Soviet-backed SWAPO guerrillas to agree by Monday to a cease-fire that would take effect March 15. This would set off the U.N. settlement plan culminating elections in September.
