The rooms are for small to mid-sized conferences with a maximum capacity of 160 people.
Created by M&C Saatchi, the campaign aims to convey the message that the hotel's legendary service now extends to meetings and conferences.
Each execution features a solid silver object - a pencil, paper clip and microphone - and a headline reading, 'You get a higher class of conference at Mandarin Oriental'. Ian Thubron, chief executive officer of M&C Saatchi Greater China, said: "Silver service is the highest level of service according to traditional dining etiquette. The mention of 'higher' and 'service' in the headline interplays with the fact that everyday objects are now silver to communicate this level of service."
