Copper prices settled higher Monday following news of increased manufacturing activity in China, the world's second-largest economy.
A report out from HSBC revealed activity in China's manufacturing sector expanded this month. That's the first time the measure has shown a rise in manufacturing this year, a possible sign that measures taken by Beijing to bolster growth are starting to work.
Copper for July delivery rose 3 cents to settle at $3.15 a pound on Monday.
China is the world's biggest buyer of the industrial metal, so an increase in manufacturing implies stronger demand. Copper prices are still down more than 7 percent this year, mainly because of concerns that China's economic growth was slowing.
