The number of Koreans on Forbes magazine's latest list of the World's Billionaires increased to 16 from 11 last year, with Samsung Group chairman Lee Kun-hee again ranked the richest man in the country.

Lee's ranking on the list, which was released Wednesday, dropped five notches to 105th, although his fortune grew by US$1.4 billion to $8.6 billion. He placed ahead of Steve Jobs, the CEO of Samsung's rival Apple, who ranked 110th with $8.3 billion.

Hyundai Motor chairman Chung Mong-koo retained the title of Korea's second richest person for a second straight year, but his worldwide standing jumped from 249th to 162nd as his wealth nearly doubled to $6 billion.

Former GNP leader Chung Mong-joon also doubled his fortune to $3.2 billion, pushing him up two notches from fifth to third among Koreans and a whopping 300 notches on the global ranking to 347th.

Lee Jae-yong, president of Samsung Electronics, ranked among the top 500, placing 488th with $2.4 billion. Kyobo Life Insurance chairman Shin Chang-jae and Hyundai Motor vice chairman Chung Eui-sun shared 564th place, each with a fortune of $2.1 billion.
