AIA is headquartered in Central, Hong Kong, with a presence in 18 markets in Asia-Pacific, with wholly-owned branches and subsidiaries in Hong Kong, mainland China, Taiwan, Macau, South Korea, Singapore, Thailand, Malaysia, the Philippines, Indonesia, Vietnam, Brunei, Cambodia, Myanmar, Australia, New Zealand, Sri Lanka and a 49% joint venture in India.

In August 2013, AIA became the official shirt partner of the English Premier League football club Tottenham Hotspur.

On 1 December 2009, AIG sold preferred equity interests in two newly formed international life insurance subsidiaries, American International Assurance Company, Limited (AIA) and American Life Insurance Company (ALICO), to the Federal Reserve Bank of New York to reduce its debt by US$25 billion.

However, on 2 March 2010, Prudential PLC, a UK-based financial services and securities company, announced that it would buy AIA for US$35.5 billion.

AIA also entered into an exclusive 20-year bancassurance agreement with NDB, one of Sri Lanka's largest financial conglomerates with a nationwide bank branch network.
