I read with dismay "An Erosion of Support" {op-ed, Sept. 21} by Rowland Evans and Robert Novak, which alleged that "U.N. sanctions are under assault from two sources: Iran and China. ... Beijing is pondering undercover trade deals to set itself up for preferential oil treatment when the gulf crisis ends. ... The Chinese are bargaining with Baghdad." Such an allegation is totally untrue, with no factual basis whatsoever.

China has been firm and unequivocal in its opposition to the Iraqi invasion and annexation of Kuwait. It demands that Iraq immediately, unconditionally withdraw all its troops from Kuwait and calls for the restoration of the sovereignty, independence and territorial integrity of Kuwait and the safe return of all foreign nationals in Kuwait and Iraq to their home countries.

As a permanent member of the U.N. Security Council, China voted in favor of the Security Council Resolution 660, which condemns Iraq's invasion and annexation of Kuwait and the Security Council Resolution 661 on imposing sanctions on Iraq. Subsequently, China voted for all the other pertinent resolutions, seven in all, that the Security Council has adopted. China has strictly implemented all the resolutions.

Immediately following the Iraqi invasion of Kuwait, China stopped its military sales to Iraq.

On the question of delivering foodstuffs to Iraq in humanitarian circumstances, China voted in favor of Security Council Resolution 666. It is emphasized in the resolution that it is for the Security Council to determine whether humanitarian circumstances have arisen and that foodstuffs should be provided through the United Nations in cooperation with the International Committee of the Red Cross, or other appropriate humanitarian agencies. China has not provided any foodstuffs or medicine to Iraq since its invasion of Kuwait.

All this shows that China is serious in playing its role as a permanent member of the Security Council and in fulfilling its responsibilities under the U.N. Charter for the maintenance of international peace, security and justice. China has contributed significantly to forming a united international response against Iraqi invasion and annexation of Kuwait.
