John Leung, owner of Wan Jun gift shop in Newport Court, said his rates bill was due to rise almost 30 per cent, from £38,000 to £49,000, and could mean he has to close. “On top of my rent of £60,000 I have to find nearly £2,000 a week,” he added. “I cannot trade longer hours than I do already so what can I do?” Restaurateur C T Tang, chairman of the London Chinatown Chinese Association, said business was already tough due to the uncertain economic climate, with Christmas corporate bookings down by half.
