Even before Konoe had been recalled, the army had already planned an invasion of French Indochina. The invasion would secure needed resources to wage war with China, cut off western supply of Kuomintang armies, put the Japanese military in a strategic location to threaten more territory, and would hopefully intimidate the Dutch East Indies into supplying Japan with oil. The US responded with the Export Control Act, and increased aid to Chang. Despite this response foreign minister Yosuke Matsuoka signed the Tripartite Pact on 27 September 1940 over the objection of some of Konoe's advisors including former Japanese ambassador to the US Kikujiro Ishii. In an 4 October press conference Konoe said that the US should not misunderstand the intentions of the tripartite powers, and should help them to build a new world order. Additionally he said that if the US did not end its provocative actions, and deliberately chose to misunderstand the actions of the tripartite powers, there would be no option left but war. In November 1940 Japan signed the Sino-Japanese treaty with Wang Jinwei, who had been a disciple of Sun Yat-sen and headed a rival Kuomintang government in Nanjing. But Konoe's Government did not relinquish all held territory to Jinwei's government, undercut its authority, and Wang's government was largely seen as an illegitimate puppet. In December 1940 the British reopened the Burma road and lent 10 million pounds to Chang's Kuomintang. Konoe recommenced negotiations with the Dutch in January 1941 in an attempt to secure an alternate source of oil.
