Four U.N. human rights experts said in a letter revealed on Tuesday that the exclusion of students at Korea University from the Japanese government's cash handout program to mitigate financial difficulties amid the coronavirus pandemic was discriminatory.

The letter was sent to the government in February, and a month later the financial aid program ended. But Japan ignored the experts' views at that time, denying the claim in April that the program, which no longer existed, had discriminated against such minority students.

The letter had been sent by Tendayi Achiume, special rapporteur on contemporary forms of racism, racial discrimination, xenophobia and related intolerance, and three other experts on the right to education, human rights of migrants and minority issues.
