Beijing is considering turning a temporary restriction on vehicles - a system based on odd-even license plate numbers that was used during the recent APEC meetings - into a long-term policy, drawing praise as well as concerns from the public.

"We have received much positive feedback on the odd-even license plate traffic restriction during the APEC meetings, suggesting that we make it a routine regulation, even on weekends, so we will further discuss and hold hearings on the suggestion," said Li Shixiang, deputy mayor of Beijing, on Wednesday.

But the decision to consider the change does not mean the tough restriction will be implemented soon, Li said.
