Prime Minister Najib Razak pledged in 2010, shortly after taking office, to reform controversial decades-old affirmative-action policies for Muslim Malays, seeking to halt a flood of minority voters to the opposition.
But he reversed course this month with a slate of new perks to placate conservatives in his Malay ruling party who are upset over a weakened mandate he won in May elections in which minorities continued to snub Najib.
"Of course, I am very disappointed," said H Y Chong, an ethnic Chinese lawyer.
Chong decided after the Malay-led 56-year-old coalition government retained power in May that she would emigrate to neighbouring Singapore, joining a flow of educated Chinese and Indians that economists say threatens Malaysia's competitiveness.
"This proves Prime Minister Najib is further sidelining the non-bumiputra," she said.
Muslim Malays and smaller indigenous groups - known as "bumiputra", or "sons of the soil" - make up more than 60 per cent of Malaysia's 28 million people.
Chinese make up a quarter of the population. Ethnic Indians comprise about eight per cent.
The policies are credited with helping create a Malay middle class and maintaining harmony despite tensions.
But critics say they have become a millstone in a competitive global economy and are abused by the Malay elite.
