Philippine President Rodrigo Duterte said on Thursday he would extend his ban on sending workers to Kuwait to include other countries if investigations showed Filipinos were being seriously abused by employers elsewhere. The Philippines has called all its nationals to leave Kuwait after a Filipino migrant worker was found dead in a freezer. The gruesome incident is the latest in what Manila calls a pattern of abuse in the Gulf state where migrant workers are often treated as domestic slaves. The Philippines serves as a “model” in terms of support for its migrant workers, the World Bank said. Some 2 million Filipinos work overseas, according to government data and dollar remittances account for 10 percent of the economy.
