text: sanctions Committee has, on the basis of the information supplied, been able to establish definitively that a breach had taken place, whether knowingly or unknowingly. 28. This is the crucial problem to which we as the international community have to address ourselves. Some of the proposals which figure in section IV of the report assume that it is an easy matter to establish that an evasion 4 has taken place. But in fact if these proposals were adopted, the sufferer would be the bona fide trader. Unless there were a marked improvement in the detection of breaches -and these proposals do not help on this-the man who is determined to evade sanctions would be able to rely on not being found out; and unless he were found out the measures would be inoperative. Such proposals would indeed be paper sanctions, and my delegation could not endorse them. To give one example, all those who have participated in the work of the sanctions Committee know well that time out of number the Committee receives replies from Governments stating that the contract or the bill of lading or some other document they had examined had been specifically endorsed to the effect that the goods must not be or were not of Southern Rhodesian origin. I am not saying that in all these cases an evasion had in fact taken place. But one must have one’s doubts about the efficacity of such a proviso when the odds are strongly against the perpetrator of an evasion being found out. I must repeat, therefore, that it is at the point of arrival of goods that action has to be taken; and there are effective methods which, provided they are properly applied, can help the authorities in their detection of falsifications.
