SINGAPORE, April 23 (Reuters) - London copper futures edged lower on Wednesday ahead of reading on China's manufacturing activity, with a further contraction likely to cut the appetite for risky assets, although nickel hit the highest in more than 14 months on tighter supply.
HSBC's Purchasing Managers' Index for China, due out at 0145 GMT, has been below 50 since January, showing small Chinese manufacturers have been struggling this year amid slower economic growth. A further decline may sow concern among investors who were relieved last week's first-quarter gross domestic product data was slightly ahead of market expectations.

* LME nickel touched an early peak of $18,440 a tonne, the highest since mid-February last year. Tight supply courtesy of an Indonesian ban on mineral ore exports had fueled a 32 percent jump in nickel prices this year, with Indonesian exports of nickel ore to top buyer China down to less than a million tonnes in March from an average of 3.4 million tonnes a month last year.
