Is cosmopolitan, interracial future the best vision for global justice?

Courts and the rule of law are the best vision for global justice. There are international courts where heads of state can be brought in front of in exteme circumstances.

There are santions that can be applied at a Global level too by the United Nations such as those being currently considered regarding oil and other supplies to North Korea.

I have no idea what interracial justice means or what the term is expected to represent in this context? Diversity at the court judging level perhaps? Similarly cosmopolitan seems to have little relevance here and maybe something lost in translation.

Global justice systems have been utilised in the past such as post Kosovo, post the collapse of Appartheid in South Africa (the truth and reconciliations hearings) and the war trials after WW2
