Copper is up on supply fears amid labor discussions at BHP Billiton's Escondida mine in Chile, but technical trading has also magnified the price increase. Traders have reduced their bets on falling prices and copper has climbed back above the symbolic $7,000-a-ton barrier. Those factors add momentum to copper buying, Commerzbank analysts say in a note. Investors are also watching for Chinese import, export and trade balance data due Friday. (david.hodari@wsj.com; @Davidhodari)
