"All races are equal, but some are more equal than others!"

Explanation: After WW1, the League of Nations was formed in the hopes of avoiding another war like it in the future. During the proceedings establishing the basic rules and axioms of the League, Japan, as the only majority non-white major power at the time, proposed a clause mandating the recognition of racial equality between the League of Nations. If accepted, this would have been a major step forward in dismantling the then-weakening notion of white racial superiority.

Notably, a majority of the members forming the League voted for it, and no votes against it were cast!

Unfortunately, the archracist American President Woodrow Wilson, who had reversed what meagre racial progress had been achieved in the US under his domestic administration, was chairman of the meeting. He insisted that that proposal alone needed unanimous support to pass, and not just majority support, despite majority support being the basis for most other proposals during the formation of the League.

That aside, Imperial Japan at this time was not quite the anti-racist polity is sought to portray itself as - while it very loudly proclaimed itself the defender of ‘colored peoples’ and of a united, ‘brotherly’ union of East Asian peoples, the truth was that racial minorities in the very expansionist Japanese Empire were subject to official discrimination based on pseudoscientific racism of Japan’s own formulation, which conveniently placed Japanese people as the ‘highest’ on the racial hierarchy.
