In September 1943, the Emperor and Tojo agreed that Japan would pull back to an "absolute defense line" in the south-west Pacific to stem the American advance, and considered abandoning Rabaul base, but changed their minds in face of objections from the Navy. In November 1943, the American public's reaction to the Battle of Tarawa led Tojo to view Tarawa as a sort of Japanese victory, believing that more battles like Tarawa would break American morale, and force the U.S. to sue for peace. Moreover, Tojo believed that the Americans would become bogged down in the Marshalls, giving more time to strengthen the defenses in the Marianas. In late 1943, with the support of the Emperor, Tojo made a major effort to make peace with China to free up the 2 million Japanese soldiers in China for operations elsewhere, but the unwillingness of the Japanese to give up any of their "rights and interests" in China doomed the effort. China was by far the largest theater of operations for Japan, and with the Americans steadily advancing in the Pacific, Tojo was anxious to end the quagmire of the "China affair" to redeploy Japanese forces. In an attempt to enlist support from all of Asia, especially China, Tojo opened the Greater East Asia Conference in November 1943, which issued a set of Pan-Asian war aims, which made little impression on most Asians. On January 9, 1944, Japan signed a treaty with the puppet Wang regime under which Japan gave up its extraterritorial rights in China as part of a bid to win Chinese public opinion over to a pro-Japanese viewpoint, but as the treaty changed nothing in practice, the gambit failed.
