HANOI, June 14 (Reuters) - Copper prices dipped on Monday in tepid trade due to a holiday in top consumer China, and suppressed by fears of measures that the Chinese authorities could take to curb commodity prices.
Three-month copper on the London Metal Exchange fell 0.4% to $9,967 a tonne by 0739 GMT. Aluminium rose 0.5% to $2,477 a tonne and nickel increased 0.7% to $18,350 a tonne, while tin fell 0.5% to $31,400 a tonne.
The Shanghai Futures Exchange is closed for a holiday.
China plans to release state reserves of nonferrous metals copper, aluminium and zinc in a programme set to last until the end of 2021, data provider Shanghai Metal Exchange Market and Chinese analysts said.
The move came as China's state planner last week renewed its pledge to step up monitoring of commodity prices, as domestic producer inflation hit its highest in more than 12 years.
LME copper has risen 28% so far this year and hit a record high last month.
"Beijing as we know has made it very clear that driving up metals prices with speculative activity is unacceptable. This message seems to have hit home as can be seen in the low turnover figures," said Malcolm Freeman, director of UK brokerage Kingdom Futures.
