In 2010, Chinese companies invested about $17 billion in Brazil, a dramatic rise from the approximately $300 million invested a year earlier, according to Brazilian economic think tank SOBEET, which tracked the inflows.

China is already Brazil’s biggest trading partner, replacing the U.S. two years ago. China consumes vast amounts of Brazilian commodities such as iron ore, soybeans and oil.

RECALL

1,000 BlackBerry tablet computers recalled

SAN FRANCISCO — BlackBerry smartphone maker Research In Motion Ltd. has recalled about 1,000 of its BlackBerry PlayBook tablet computers due to defective operating software that can make it impossible for users to set up the device.

The Waterloo, Ontario-based gadget maker said in a statement Monday that it learned that the affected tablets were shipped with software “that may result in the devices unable to properly load software upon initial setup.” Only PlayBooks with 16 gigabytes of memory were affected, RIM said, and the majority of them had not yet been sold to customers.

RIM said it is working to replace the affected tablets. Customers that did end up with one that can’t load the software correctly during setup can contact the company for help, RIM said.

The issue was reported on Saturday by tech blog Engadget, which said the affected PlayBooks had been shipped to Staples Inc. stores. RIM did not comment on whether this was the case, and a Staples spokeswoman did not return a request for comment.
