KUALA LUMPUR: The Industrial Production Index grew by 2.7 per cent in May from 3.0 per cent in April.
The Statistics Department said the slower pace was due to the 1.1 per cent decline in the mining index.
A 5.2 per cent decrease in the crude oil index contributed to the decline, although the natural gas index had increased by 4.5 per cent.
The manufacturing and electricity sectors expanded by 3.6 per cent and 9.6 per cent, respectively.
According to the Statistics Department, the manufacturing sector's growth was led by the electrical and electronics products (8.3 per cent), petroleum, chemical, rubber and plastic products (5.1 per cent) and non-metallic mineral products, basic metal and fabricated metal products (5.8 per cent).
The electricity sector output rose by 9.6 per cent in May.
