An article in the Wall Street Journal reports that the New York Times plans to launch an online Brazilian edition in 2013.
The digital edition will contain Portuguese translations of articles that appeared in English in the newspaper, as well as original content aimed specifically at Brazilian readers. The Brazilian edition will contain about 40 articles each day, and of those, about a third will be local content.
The following quote by NY Times Chair Arthur Sulzburger is from the article, and summarizes the reasons for the Times developing a Brazilian edition:
"Brazil is an international hub for business that boasts a robust economy, which has brought more and more people into the middle class," said New York Times Chairman Arthur Sulzberger Jr. "As the world gets smaller and digital technology enables us to reach around the globe to attract readers with an interest in high quality news, Brazil is a perfect place for The New York Times to take the next step in expanding our global reach."
Note that Sulzburger specifically singles out Brazil's importance as a center for international trade, its strong economy, and the growth of its middle class as primary reasons for launching a Brazilian edition of the Times.
