In a surprise move, China raised its key interest rate and the country's largest offshore oil explorer has posted record first quarter financial results.
China's central bank raised its benchmark one-year lending rate by 27 basis points to 5.85 percent.
China's first interest rate increase in 18 months is seen as an attempt to cool a boom in investment and credit growth. China's economy grew by more than 10 percent in the first quarter, raising worries about overheating, which could spark inflation and other problems.
The central bank's benchmark one-year deposit rate remains unchanged at two-and-a-quarter percent.
China's largest offshore oil explorer, CNOOC, says its total revenue for the first quarter to March rose 45 percent from a year earlier, to more than $2 billion.
CNOOC's chief financial officer Yang Hua says the company's earnings benefited from the soaring price of oil. The company achieved an average oil price of more than $58 a barrel, a 39 percent increase from a year earlier.
Yang says earnings were also boosted by stable production growth in the first quarter.
"Our total production in Q-one [first quarter of the year] increased by nine and a half percent year over year, mainly due to strong production growth in Bohai Bay," said Yang. "Offshore China, our oil and gas production increased approximately 11 percent year over year."
