Rarely does Singapore use strident language or take on a visibly active role in foreign policy as it has over the increasing bloodshed in Myanmar.
Worries over regional instability and the credibility of the Association of Southeast Asian Nations (ASEAN) bloc in the face of China's increasing power are at the forefront of the unusually strong stance taken by the country, several analysts say.
Another factor is that Singapore is the largest foreign investor in Myanmar, partly through investments by multinationals based in the island republic.
