I don't know enough about 1930s American race relations to know whether or not that's an accurate description of the New Deal, but I do know that it's definitely not the most incontrovertible example of a racist FDR policy she could have chosen.
People, especially on the left, don't care much about racism against Asians these days because they're a "privileged" group. Just look at how Harvard is justifying its anti-Asian policies by claiming Asians have "bad personalities" and getting leftist professors to stick up for them.
