On Friday price of copper dropped to the lowest level in a week, Reuters reports. As dollar strengthens, copper is close to show the biggest weekly drop since April. The reasons for such market drop are slower economy of China, the biggest metal buyer in the world, as well as threat of US tariffs on Chinese import.

Depening trade tensions between two countries will put downward pressure on copper market, experts think.

Not very optimistic news from the US, Europe and China together with rising dollar and falling currencies of emerging countries will restict further growth.

Price of LME copper fell by 0,5% to $7140 per ton. Price of industrial metal dropped from the highest level in four and a half years that was reached last week due to concerns over deliveries from the largest mine in the world.

Production volumes of non-ferous metals in China, including copper, aluminum, lead, zinc and nickel, grew by 4,3% in May compared to last year to 4,55 million ton. Aluminum output rose by 1,5% to 2,79 million ton. Copper inventories decrease by 1,2% during last week.
