Cambodia's Prime Minister Hun Sen on Friday took aim at the foreign minister of Malaysia for being "arrogant" and impolite after its top diplomat voiced concern about the premier's controversial meeting with Myanmar's junta.

Malaysia's Foreign Minister Saifuddin Abdullah last week said some Association of Southeast Asian Nations (Asean) members had reservations about Hun Sen's Jan 7 visit to Myanmar while chair of the bloc, which risked being interpreted as Asean recognition of the generals.
