(Adds analyst comment, updates prices) BEIJING, March 1 (Reuters) - Shanghai copper prices fell for a fourth day on Thursday to touch their lowest level in more than two weeks as the dollar strengthened and stock markets declined, but other metals gained ground after upbeat manufacturing data from top consumer China. The private Caixin/Markit Manufacturing Purchasing Managers' Index for February beat expectations to reach its highest in six months, a day after China's official factory activity reading raised concerns of a sharper-than-expected slowdown in the world's second biggest economy this year. "The impact was probably the result of ongoing production constraints due to the environmental controls in China," ANZ said of the offical PMI reading. FUNDAMENTALS * SHFE COPPER: The most-traded copper contract on the Shanghai Futures Exchange had slipped 0.5 percent to 52,490 yuan ($8,280.49) a tonne by 0459 GMT. It earlier touched its lowest since Feb. 13 at 52,120 yuan a tonne, and is down 2 percent so far this week. * LME COPPER: Three-month copper on the London Metal Exchange rose 0.4 percent to $6,956 a tonne, having fallen by 1.3 percent in both the two previous sessions.
