The government is considering a move to tighten rules for the import of foreign cars into Malaysia, Prime Minister Dr Mahathir Mohamad said.

"However, some of the developed countries are imposing certain conditions, such as the Euro 5, which defines the limits of carbon monoxide emissions. Other countries impose agriculture taxes against (us)," he cited.

"But, we remain very open, we allow all cars, including those made from ‘Milo tins’ to enter Malaysia," he said.
