SYDNEY, July 18 (Reuters) - Copper prices held firm on Tuesday, maintaining gains made in the wake of strong Chinese economic data that boosted the outlook for metals demand.
China's economy expanded at a faster-than-expected 6.9 percent in the second quarter, setting the country on course to comfortably meet its 2017 growth target, data released on Monday showed.
"Sentiment continues to improve in the industrial metals complex after strong economic data from China yesterday," ANZ said in a note.
"This data appeared to boost confidence in the country's ability to weather the regulatory reforms that are appearing to tighten monetary conditions in China."
