China, Argentina seek closer cooperation

BUENOS AIRES - Argentina's President Cristina Fernandez checked into a Buenos Aires hospital for treatment of "an infectious fever," according to a statement issued by the government.

"She decided to check herself in for observation and treatment," said the statement, which was signed by her medical team.

The 61-year-old, two-term president had an operation last year to remove blood that pooled on her brain. She had since resumed a full schedule but took several days off last month with a sore throat.
