MANILA, July 6 (Reuters) - Chinese steel prices recovered from early losses to trade firmer on Friday as Beijing's efforts to cut production capacity as part of its pollution fight have countered concerns over U.S. tariffs on $34 billion of Chinese goods that have just begun.
The U.S. tariffs took effect as a deadline passed on Friday, and China vowed to respond, bringing the world's two biggest economies even closer towards an all-out trade conflict.price of construction steel product rebar on the Shanghai Futures Exchange SRBcv1 closed up 0.2 percent at 3,780 yuan ($569) a tonne, after falling as much as 1.1 percent in morning deals.
Hot rolled coil SHHCcv1 , used in manufacturing, was off 0.2 percent at 3,851 yuan, having dropped by up to 1.5 percent earlier.
Chinese stocks have also risen and other commodities including copper CMCU3 have cut losses.
For steel futures, China's sustained measures to reduce capacity have lent support to prices, said Helen Lau, an analyst at Argonaut Securities in Hong Kong.
"If a lot of steel capacity will be constrained in order to meet these air quality targets, then domestic steel supply will become tight," said Lau.
China said this week it will shut more outdated steel and coke capacity in the next three years as part of its battle against pollution. Separately, China's top steelmaking city of Tangshan ordered steel companies and coke producers to meet ultra-low emissions targets.drop in weekly steel inventory in China suggested demand remained firm in the world's largest consumer and producer.
