Austria will follow the United States and Hungary in backing out of a United Nations migration pact over concerns it will blur the line between legal and illegal migration, the right-wing government said on Wednesday.

The Global Compact for Safe, Orderly and Regular Migration was approved in July by all 193 member nations except the United States, which backed out last year.

Hungary's right-wing government has since said it will not sign the final document at a ceremony in Morocco in December. Poland, which has also clashed with Brussels by resisting national quotas for asylum-seekers, has said it is considering the same step.
