Chile's state-owned miner Codelco begins copper exports after port strike

Chilean state-owned mining company Codelco has resumed shipments of copper after a port strike blocked exports in the world's top copper producing nation.

Chief Executive Officer Thomas Keller says shipments will return to normal in about a month.

Port workers returned to work Saturday after reaching a deal to end three weeks of strikes that halted exports of copper, fruit and wood pulp.

The strike caused concerns because Chile produces a third of the world's copper and its solid economy is built around exports of minerals.

Labor unions at Codelco and private mining companies plan to announce a national strike for Tuesday.

Keller told foreign correspondents Monday that he doesn't expect increased labor unrest ahead of this year's presidential elections to affect copper output.
