asked the Minister of Economic Warfare whether he is aware that 2,140,000 barrels of American oil have arrived at Vladivostock since September, and what steps he has taken to prevent this addition to the strength of the enemy?

I regret that I am unable to state whether or not the figure mentioned by the hon. Member, which I presume is supposed to cover the period from 1st October to 31st March, is accurate. The official monthly trade returns published by the United States Government do not distinguish exports of oil or any other commodity except cotton by country of destination. I have seen various figures from different sources relating to this traffic but, as these differ from each other, I would prefer to reserve judgment on them for the present. As regards the second part of the Question, I have nothing to add to the reply given to the hon. Member for Central Bristol (Lord Apsley) on 21st March.

May we have an assurance that firm and definite steps are being taken to prevent this increase of strength to the enemy?

As I indicated in the answer to which I have referred the hon. Member, these imports of oil, although much above the 1938 figures, are not in excess of the quantities imported in some previous years. I believe that this oil is required by the Soviet for their own use in the Far East and is not being re-exported to Germany.

Has any assurance been asked for or obtained from the Soviet Government that it will not be re-exported?

Is there any case in history in which petroleum has been sent 6.000 miles by railway train?

asked the Minister of Economic Warfare whether, in view of the fact that the total exports from the Netherlands Indies to Vladivostock between January and August, 1939, were 520,000 kilograms, whereas from September to December, 1939, they rose to 10,611,000 kilograms, he will state what steps are being taken to prevent these supplies reaching Germany?

The hon. Member may be assured that steps are being taken in this matter, but he will appreciate that it would not be in the public interest to state what these measures are.

May we have an assurance that the steps taken will be in time and not too late?

They will be taken as rapidly as possible.

asked the Minister of Economic Warfare what steps are being taken to prevent the export to Germany from the ports of Dubrovnik and Susak, of bauxite, lead ore, cement and other articles?

Reports in the Press have been brought to my notice of German ships loading such cargoes in Yugoslav ports. According to my information, however, there has only been one such cargo loaded up to the present. His Majesty's Government are carefully watching this traffic and can be relied upon to take any steps to check it which they consider practicable.

Do I understand that the Minister has no information whatsoever on this subject, except what he has seen in the Press? If so, is it not a grave reflection on our representatives abroad?

I have information of one ship, and one ship only.

asked the Minister of Economic Warfare whether His Majesty's Government are taking any steps to prevent industrial diamond exports from this country reaching Germany?

The export of industrial diamonds from this country is prohibited except under licence of the Board of Trade. A committee having a special knowledge of the diamond trade, on which the Ministry of Economic Warfare is represented, has been set up to advise the Board of Trade on all applications for export licences, to ensure that no industrial diamonds reach enemy territory.

Is the Minister aware that it is alleged that a number of diamonds, exported under licence, go to Holland, and through Holland to the Germans? Has he any information on that matter?

I am not aware of that allegation. This trade is being carefully watched, but if the hon. Member has any particular information of value I shall be very happy to have it.
