Since the mid-1960s Southeast Asia has faced a potentially wide-ranging security threat. Well before the events of September 11, the region was enduring a slump in exports and a falloff in foreign investment as Western firms headed to China. Even Singapore’s economy, the region’s strongest, probably shrank by 2% in 2001, while Indonesia, the weakest player, is struggling to avert a new foreign debt crisis.
Now the region is being seen overseas as a breeding ground for international terrorists. Foreign businesses have stopped sending execs to the region to explore new opportunities, while companies are beefing up security at their offices and homes. Clearly, the region’s governments need to show the world they can keep the peace. That requires achieving a tricky balancing act: Authorities must provide adequate security to foreign firms without being alarmist and scaring them off completely.

A. of the economic slowdown

C. of the dropdown in foreign investments
