Indonesia will soon ratify the UN Convention on the Rights of Migrant Workers and Their Families in order to protect the rights of its citizens employed abroad, ANTARA quoted an official as saying. "The government will ratify the convention because Indonesia is one of the biggest exporters of migrant workers," Foreign Affairs Ministry's official Suryana Sastradiredja was quoted Friday by the national Antara news agency as saying. Ratifying the convention is part of efforts to lay an international legal basis for the protection of migrant workers' rights, he said. Nearly 4 million Indonesian citizens currently work abroad with 76 percent of them employed as domestic helpers.
