There still is a possibility of peacefully settling the present conflict between China and Japan, provided that the latter be ready to accept the former's proposal for negotiations. So long as diplomatic relations between the two countries have not been formally severed, negotiations could be started soon. Now that the situation has become extremely tense, it is imperative to give an immediate answer to the question of war or peace. This, however, does not necessarily mean that it is too late to begin negotiations for a peaceful settlement. It is believed that the present difficulties will be surmounted only if leaders of the Japanese Government show statesmanship supported by courage.
The time seemed to have at last arrived when there would be peace between the two countries. Formal negotiations were about to be commenced. However, the Oyama Incident in Shanghai caused the peace move to end in total failure....
....At about 1830 on 9 August, Lt Isao Oyama, commander of the Western Detachment, Shanghai Special Naval Landing Force together with Seaman 1st Class Saito, the driver, were murdered by the Chinese Peace Preservation Corps while riding in an official car on the road outside Hung-Chiao Airfield in the western part of Shanghai. Diplomatic negotiations, as usual, made no progress. The incident was used as an excuse by both sides, however, and a sharp increase was made in the forces. Eventually this resulted in the clash in Shanghai.
Can anyone verify the importance of this incident?
