Myanmar has stopped sending workers to Muslim-majority Malaysia as relations sour over a bloody military crackdown on the Buddhist country's Rohingya minority.
The move came after Malaysian Prime Minister Najib Razak lashed out at Myanmar's de facto leader Aung San Suu Kyi for allowing "genocide", during a rally in Kuala Lumpur that drew thousands of people.
The crowds were protesting against a military crackdown in Myanmar's western state of Rakhine that has pushed more than 20,000 Rohingya Muslims into Bangladesh.
Late Tuesday Myanmar's immigration ministry said it had stopped issuing new licences for its nationals to work in wealthier Malaysia, for years a top destination for migrant labour.
"Myanmar has temporarily stopped sending workers to Malaysia from 6/12/2016 because of the current situation in Malaysia," it said in a statement, without elaborating.
Survivors have told AFP horrifying stories of gang rape, torture and murder at the hands of Myanmar security forces, while dozens have died trying to cross the river that separates the two countries.
Buddhist-majority Myanmar has long discriminated against the stateless Rohingya and the recent crisis has galvanised protests in Muslim countries around the region, including Malaysia.
"We want to tell Aung San Suu Kyi, enough is enough... We must and we will defend Muslims and Islam," Najib said at Sunday's 5,000-strong rally.
"The world cannot sit and watch genocide taking place."
A Malaysian government minister has also called for a review of Myanmar's membership of the regional Asean bloc.
Myanmar officials have denied the allegations of abuse and Suu Kyi has told the international community to stop stoking the "fires of resentment".
Myanmar has also summoned Malaysia's ambassador to protest at Najib's accusations of ethnic cleansing.
Malaysia hosts tens of thousands of Myanmar workers, most of them in low-paid jobs in factories or hospitality industries.
