On September 12, one month after the Battle of Shanghai began, China formally brought the case against Japan to the League of Nations. Again, the League was not able to formulate any effective sanctions against Japan other than an October 4 statement that gave China "spiritual support." The United States was not a member of the League and Great Britain and France were reluctant to challenge Japan. Of all the major Western powers, only the United States seemed able to act more since it was not embroiled in the volatile European affairs.
