METALS-Copper climbs on solid China manufacturing report, softer dollar

MELBOURNE, April 30 (Reuters) - London copper and aluminium climbed on Monday as the dollar eased from three-month highs and trade stayed quiet given a holiday in China and ahead of a slew of monthly manufacturing reports from the world's top user of metals. Growth in China's vast manufacturing sector eased only slightly in April in a sign of broad economic resilience, though slowing export orders pointed to risks to the outlook amid a simmering Sino-U.S. trade row.
