LONDON, Jan 10 (Reuters) – Copper steadied on Thursday as investors grew weary of mixed signals from U.S.-China trade talks and poor China data, though a weaker dollar and still tight supply-side conditions underpinned the metal. China said the three days of talks in Beijing had established a “foundation” to resolve the two country’s differences, but gave virtually nothing in the way of details on key issues at stake. At the same time, the world’s biggest base metals consumer released data showing factory-gate inflation rose at its slowest rate in more than two years. “The question is how sustainable the (China-U.S.) developments will be. It’s given the market breathing space but there’s still no substantial information communicated,” said Xiao Fu, head of commodity market strategy at Bank of China International.  Underpinning copper however, the dollar languished near a 3-month low, making dollar-priced metals cheaper for non-U.S. investors.
