In July 1941 when the Japanese occupied southern Indochina, Britain, the United States and the Netherlands imposed economic sanctions, freezing Japanese financial assets and cutting Japan from its supplies of oil, tin and rubber. The sanctions were aimed at pressuring Japan to abandon its involvement in China; instead, the Japanese government planned to seize the resources of South-East Asia from the European nations by force. Both the Japanese navy and army were mobilised, but for the moment an uneasy state of cold war persisted. British Commonwealth reinforcements continued to trickle into Malaya. On 2 December, the battleship HMS "Prince of Wales" and the battle-cruiser HMS "Repulse", escorted by four destroyers, arrived in Singapore, the first time a battle fleet had been based there. (They were to have been accompanied by the aircraft carrier to provide air cover but she had run aground in the Caribbean en route.) The following day Rear-Admiral Spooner hosted a dinner attended by the newly arrived Commander-in-Chief Eastern Fleet, Admiral Sir Tom Phillips, and Percival.
