MELBOURNE, Jan 22 (Reuters) - London copper on Monday edged higher from the $7,000 level that has marked support so far this year, as an upbeat mood among Japanese manufacturers added to a brightening picture for global metals demand. A resilient property market in China and a pick up in global manufacturing growth are adding to a rosier outlook for this year, said analyst Helen Lau of broker Argonaut Securities in Hong Kong. "The global economy is stronger, so China's exports will be better than last year. Unless China has a major policy to tighten the market, we think the demand picture overall will be slightly more optimistic this year." In the near term, however, a seasonal soft patch between Christmas and the Lunar New Year in mid-February, and the potential for a dollar rally could also pressure prices of some metals. "For copper there are some risks. Prices have climbed a lot, and the net long position is very high so it's very likely for either end users or investors to trim their positions."
