SINGAPORE, March 19 (Reuters) - Copper and aluminium edged up on Tuesday, supported by China's announcement to cut tax for manufacturers from next month and on expectation of a seasonally higher growth in the second quarter.
"Sentiment was largely constructive as investors continued to view China's latest policy moves as positive for metals demand," ANZ said in a note.
China will cut value-added tax for manufacturing and other sectors on April 1, Premier Li Keqiang said on Friday, adding that cuts in taxes and fees remained a key measure to cope with downward pressure on its economy.
But gains were muted as the tax cut might not translate into higher earnings for companies as they would make use of the lower tax rate to boost research and development, said analyst Helen Lau of Argonaut Securities.
China's second quarter economic growth could be at a lower pace compared to the same period last year, but it is expected to pick up from the seasonally slow first three months, which has a long holiday of Chinese New Year, Lau said.
