The Ambassador in the United Kingdom (Winant) to the Secretary of State

No. 5005

Sir: I have the honor to refer to the Department’s strictly confidential instruction No. 1538 of July 1,7 transmitting a strictly confidential memorandum entitled “China’s War Potential: Estimate”. In accordance with the suggestion contained therein, we left a copy of the memorandum in confidence with Mr. Ashley Clarke. He expressed his appreciation therefor and his keen interest in the contents. In due course he wrote us a personal letter, a copy of which is enclosed for the Department’s information. Subsequently we took occasion to call on Mr. Ashley Clarke and to talk over both the Department’s memorandum and his reply. He emphasized the general identity of views of himself and his associates with the conclusions of the memorandum, remarking that the points he has raised in the enclosed letter are, in general, minor ones.

With reference to the third paragraph of his letter, we asked whether he did not feel that the establishment of a continuous railway link from Manchuria to Singapore, with the exception of short stretches in Indo-China and Thailand, could constitute a probable immediate military advantage to Japan in the event of a Chinese collapse. This he conceded. We also inquired whether he did not feel that such a collapse would in fact release a considerable number of Japanese troops for service elsewhere. While agreeing that it would eventually, he thought that much would depend upon the form of the collapse and whether guerrilla warfare would continue as factors determining the number of troops Japan could immediately withdraw. He also agreed that Japan would probably obtain greater access to a large supply of labor and certain strategic raw materials. He went on to say that as far as the immediate effects, however, of a Chinese collapse were concerned, he felt that their principal importance would be psychological or political (along the lines indicated in the Department’s memorandum), their economic second, and the military third. At a later period, he believed, the relative importance to Japan of the military and economic aspects of a Chinese collapse would increase. The difference in the British and American points of view, therefore, is largely one of degree or emphasis, and the British fully concur with us that from every point of view a Chinese collapse would constitute a major set-back. Personally, it is his feeling that Chiang Kai-shek will never make peace with Japan and that [Page 144] such a development could only take place if the Generalissimo were, in one form or another, eliminated.

As the Department is aware, the British are always sensitive on the question of the independence of Tibet, which accounts for the mention of that territory in Ashley Clarke’s letter; but he did not appear to take the reference to that territory as “lumped with China” (Department’s memorandum—paragraph 1) too seriously.8

Respectfully yours,

For the Ambassador:
H. Freeman Matthews

Counselor of Embassy

My Dear Matthews: A little while ago you left with me informally a copy of a memorandum prepared in the Department of State on China’s war potential which the Department had kindly agreed that we should see.

When I was in Washington I raised this very question with Mr. Hornbeck and Mr. Hamilton. In the grave situation created by the cutting of the last main route connecting China with her allies, it seemed to me that a review of where we all stood as a result was a necessary preliminary to considering what remedial action was most needed. In other words, we here are only concerned with what would happen if China fell out in order to decide what you and we could do to keep her in.

The paper which you gave me answers my enquiry admirably and we have read it with the greatest interest. May I say at once that we are in close agreement with its general conclusions? While we are doubtful as to the material benefits which Japan would immediately derive and still more doubtful whether Japan could maintain herself as a continental power after ceasing to be a naval power, we hold the view that the collapse of China would prolong the war by removing a potential base for striking at Japan, by the extent to which it would relieve the strain on Japanese resources, by the adverse psychological effect it would have on all of us and by the encouragement which it would give to our enemies. For these reasons (and there are others) we share the anxiety of the authors of the memorandum to help in [Page 145] maintaining Chinese resistance and we spend much time thinking how best this can be achieved.

There are of course a few points in the memorandum which we ourselves might perhaps have expressed differently. I was surprised for example to see Tibet lumped in as part of the territory of China. In point of fact the Tibetans not only claim to be but actually are an independent people, and they have in recent years fought successfully to maintain their freedom against Chinese attempts at domination. Their distinct racial, political, religious and linguistic characteristics would seem to entitle them, therefore, to the benefits of Chapter IV paragraph 2 of the memorandum.

I should have thought that there were no advantages at all to be gained if China were to cease resistance to Japan (see pages 13 and 14)! Nor can I imagine that any of the United Nations entertain even a thought of problematical advantages to be gained by the absence of China from the Peace Conference. Finally, I wonder whether the implication of page 17 (probably quite unconscious) that no nation except the United States has been actuated by high motives in its dealings with China is not rather sweeping? So far as we are concerned, for instance, the opium wars are a long way behind us: and the abandonment of the Japanese Alliance at the Washington Conference,9 whatever else it may have been, was not an act of imperialism!

But these lesser points do not obscure the moral of the tale, which is that China has made and is making—within the limitations now imposed by her isolation—a real contribution to the united war effort and deserves that we should bend our energies to supporting her.

Yours sincerely,

Ashley Clarke

P. S. If you like we could have a talk about all this. H. A. C.
