CORRECTED - CORRECTED-Yahoo eyes operating margin of 15-20 pct in 3 yrs

(Corrects to make clear that margins will grow to 15-20 percent in three years, not at a 15-20 percent pace over three years)

SINGAPORE Nov 10 (Reuters) - Internet giant Yahoo Inc (YHOO.O) is committed to grow its operating margin to 15-20 percent over the next three years from 6 percent currently, CEO Carol Bartz said on Tuesday.

Bartz described the current operating margin of 6 pct as "terrible, terrible".

Yahoo, the top U.S. seller of online display ads, will eye growth in Southeast Asian markets such as Indonesia and Vietnam, she said at a lunch talk organised by the American Chamber of Commerce in Singapore.

Microsoft Corp (MSFT.O) said on Nov 5 its search engine partnership with Yahoo would not be limited to the United States but would be introduced around the world, once it gets regulatory approval. [ID:nT161596]

Microsoft and Yahoo had earlier this year signed a 10-year global Web search partnership to challenge market leader Google Inc (GOOG.O), a pact that U.S. and European antitrust regulators are evaluating.
