In 2006 a memorandum was presented to the prime minister by non-Muslim cabinet members asking for a review of constitutional provisions affecting the rights of non-Muslims. After protests by Muslim leaders in the governing coalition, this was withdrawn. It is forbidden for non-Muslims to try to convert Muslims, although Muslims are allowed to convert others. Malay politicians have asked the Chinese and Indian communities not to question Malay rights, for fear of igniting ethnic violence, with harmony between the races and religions being seen as a necessity.
