"In 2009, Singapore was the 11th largest U.S. trading partner with $22 billion in U.S. exports. Since the U.S.-Singapore FTA [Free Trade Agreement] entered into force on January 1, 2004, exports to Singapore have increased 73%. In addition to trade, mutual security interests strengthen ties between Singapore and the United States. A formal strategic partnership agreement outlines access to military facilities and cooperation in counterterrorism, counter-proliferation of weapons of mass destruction, joint military exercises, policy dialogues, and shared defense technology. […] Shortly after the September 11 attacks in the United States, Singaporean authorities launched aggressive operations to counter terrorist activities. Under its Internal Security Act, Singapore arrested dozens of suspected Islamic militants, 16 of whom remain in detention, as of January 2009. Many of the militants are alleged to be members or sympathizers of Jemaah Islamiyah (JI), a designated foreign terrorist organization with reported links to Al Qaeda. In 2002, Singaporean authorities reportedly uncovered a JI plot to bomb the U.S. Embassy and other Western targets in Singapore. Singapore has signed a number of multilateral and bilateral agreements focused on counterterrorism. It was a founding member of Proliferation Security Initiative (PSI), a program that aims to interdict shipments of weapons of mass destruction-related materials and was the first Asian country to join the Container Security Initiative (CSI), a series of bilateral, reciprocal agreements that allow U.S. Customs and Border Patrol officials at selected foreign ports to prescreen U.S.-bound containers."
