Police have banned public gatherings around the Queen Sirikit National Convention Center, One Bangkok Forum and 22 hotels hosting IMF-World Bank delegates until Oct 20. Police urge motorists to avoid Rama IV, Duang Phithak, Ratchadaphisek, Sukhumvit and Witthayu roads and the Na Ranong flyover, and say a vehicle-bar order may apply from 12.01am Monday to midnight Sunday if gatherings occur. No roads are closed for now. If your delivery, staff commute or customer visits run through these areas, plan extra time or use the MRT (QSNCC and Sukhumvit stations) or BTS Asok.
