The House voted 260 to 163 yesterday to continue $7 million of non-lethal aid to the non-communist resistance forces in Cambodia for another year after a brief, heated debate that showed Democrats to be divided on the emotional issue.

House members attempting to delete the aid argued that the U.S.-backed resistance that is seeking to topple the pro-Vietnamese communist regime in Phnom Penh is intertwined with the Khmer Rouge, a group described by Rep. David Obey (D-Wis.) as "hav{ing} more blood on their hands than anyone since Hitler and Stalin."

But 107 Democrats and 153 Republicans, heavily lobbied by the Bush administration, joined to support an amendment by Rep. Stephen J. Solarz (D-N.Y.) to continue the aid. Solarz contended that there was "no credible evidence that our aid is going to the Khmer Rouge." The Khmer Rouge government's policies in the late 1970s are estimated to have caused the deaths of several million Cambodians.

The vote came as part of debate on the overall $15.7 billion 1991 foreign aid bill, which passed by 308 to 117. The bill reduces military aid by $193 million from the previous year, and begins shifting priorities by channeling more money to sub-Saharan Africa, East European democracies, refugees, global warming, environmental concerns and trade development.

Left to be resolved later was the question of military aid to El Salvador. The House-passed bill withholds half of $85 million for that country unless the guerrillas break off peace negotiations. The aid would be terminated altogether if the Salvadoran government ends talks or fails to pursue its investigation of last fall's murder of Jesuit priests.

But the administration has said it will veto the foreign aid bill if it contains that language, and a House task force has been meeting with the administration on a possible compromise. Rather than face a vote on the floor yesterday, administration backers canceled plans to try amending it.

The most hotly contested amendment yesterday directly challenged administration abortion policy by channeling $1.5 million in family planning aid to Romania through two organizations targeted by the National Right to Life Committee.

The amendment, offered by Reps. William Lehman (D-Fla.) and John Edward Porter (R-Ill.), would have used the United National Family Planning Agency and International Planned Parenthood Federation for the job. But Rep. Christoper H. Smith (R-N.J.), warning of a veto of the whole bill if those two groups were included, struck them from the measure on an amendment that passed 224 to 198. Antiabortion groups charge that the agencies promote abortion as a family planning method in some countries, including coercive abortion in China.

The Smith amendment preserved $1.5 million family planning money for Romania to be used by other contractors selected by the Agency for International Development. Rep. Jan Meyers (R-Kan.), noting that the two family planning groups are already established in Romania, called the amendment "cruel and shortsighted," and Rep. Richard J. Durbin (D-Ill.) charged the antiabortion forces with conducting a "vendetta" against the two agencies.

A carefully worded bipartisan compromise requires the president to withhold the U.S. proportion of international aid to China when that aid is not for "basic human needs."

Israel continues as beneficiary of about one dollar out of five in the bill. But Obey, who chairs the foreign operations appropriations subcommittee that drafted the measure, yesterday called for an accounting of aid funds spent on the West Bank and said if any new U.S. money was used there he would support reducing aid to that country.

With the support of Rep. Ronald V. Dellums (D-Calif.), chairman of the Congressional Black Caucus, the bill also terminates military aid to Zaire, whose leader, President Seke Mobutu, was attacked by Obey for running "the largest plutocracy on the face of the earth."

The Cambodian aid issue is expected to reemerge in the Senate, where several key leaders have raised concern that the U.S. aid may be indirectly assisting the Khmer Rouge. "It's just the beginning," said Rep. Chester G. Atkins (D-Mass.), sponsor of the bid to redirect the aid to peace activities.

"The U.S. is living a lie," said Rep. Robert J. Mrazek (D-N.Y.). "The lie is that U.S. aid contributes to a peaceful solution."
