His suggestion after Indochina was occupied by the Japanese was to see if he could come to an agreement with Japan to regard it as a "neutral country like Switzerland."
In the summer leading up Pearl Harbor, the Japanese refused to come to any diplomatic agreement with the US that ruled out hostilities. They chose to remain in the Tripartite Pact. Even after Barbarossa beginning two months after they signed a neutrality pact with the USSR gave them the easiest out imaginable. Nonetheless, US diplomats tried to come to an agreement that that would prevent war with Japan.
Japan's leadership didn't want war either at this time. Yet they were willing to sacrifice absolutely nothing to actually achieve it. Yamamoto thought war was a bad idea, but still went ahead drafting war plans anyway.
It was in this environment that the Hull Note was written. Despite the terms being highly conciliatory, it's remembered as a declaration of war by Japanese nationalists on account of it calling for a withdrawal from China and recognition of the ROC's government. (Herbert Bix suggests that the biggest sticking point was that Hull didn't distinguish between Manchukuo and China.)
After the Hull Note was sent on November 26, there was radio silence from Japan. In the time between then and December 7, the US knew war with Japan would arrive at some point.
It wasn't a righteous struggle against colonialism, withholding of oil, or a Chinese charm offensive that provoked the Pacific War. The blame lays at the feet of the incompetent Imperial leadership. Those who knew a total war with the Allies would be unwinnable, but chose to gamble anyway.
