SINGAPORE, Oct 25 (Reuters) - London copper prices edged up on Friday and were set for a third straight weekly gain, buoyed by investor concern over supply disruption in top producer Chile.
The benchmark three-month copper contract on the London Metal Exchange (LME) rose 0.1% to $5,884 a tonne at 0700 GMT and was up 1.3% this week after hitting its highest in more than five weeks in the previous session.
The most traded copper contract on the Shanghai Futures Exchange (ShFE) closed 0.2% up at 47,390 yuan ($6,704.58) a tonne. The contract rose 1.4% over the week for its first weekly gain in three.
Copper prices have been supported by supply shortage fears after production disruptions at several copper operations in Chile, the world's biggest producer of the metal, amid nationwide protests.
Prices of the red metals, however, fell throughout most of Asian trading hours before rising at Friday's Shanghai close on support from lingering worries over the demand outlook.
Copper is often used a gauge of global economic health, which has been hit by an unresolved and prolonged trade war between China and the United States, the world's two biggest economies.
"Copper is currently traded as a macro," said one industry source.
