The Asian region's biggest power, China, however, has remained largely silent on the crisis involving Muslim Rohingya fleeing persecution in Myanmar and Bangladeshis seeking to escape poverty.
That reflects Beijing's longstanding aversion to such foreign intervention as well as potential unease among its neighbours over any further projection of Chinese naval power, but it also complicates any aspirations Beijing may have to be a regional leader in ways that go beyond economic ties.
"Hegemony has costs, Beijing only wants the rewards," Abuza said in an email interview.
Four Malaysian naval ships have begun searching for migrants believed to be stranded on crowded boats with little food, in the first official rescue operation since the boat people started washing onto Southeast Asian shores earlier this month.
While there have been no calls for China to become directly involved in the crisis, expectations have risen due to its growing involvement in UN peacekeeping and international relief operations, most recently sending aid to Nepal following that nation's devastating earthquakes.
China's navy has played a part in providing such assistance and has frequently transited the Andaman Sea on its way to joining anti-piracy patrols off the coast of Somalia.

Most recently, China has attracted 57 nations from inside and outside the region to become founding members of the Asian Infrastructure Investment Bank, a potential rival to existing US-backed multinational lending institutions such as the International Monetary Fund and Asian Development Bank.
India, the region's other giant, has sought to counter China's influence in its traditional backyard, while ties with Japan are hamstrung over a separate territorial dispute in the East China Sea.
