HA NOI (VNS) — The city's index of industrial production (IIP) this month increased 7.8 per cent over last month, and rose 12.1 per cent compared with the corresponding period last year, the General Statistics Office have announced.

The figures released by the office show that most industrial sectors saw IIP increase on the previous month. The exceptions were the weaving sector, which dropped 12.6 per cent, and the pharmaceutical chemistry industry, which saw its figure fall 0.2 per cent.

The mineral industry rose 21.5 per cent, processing and manufacturing increased by 7.8 per cent and electricity production recorded a 1.3 per cent hike.

IIP in the first four months of the year increased 4.9 per cent over the same period last year. Key sectors are performing well, with weaving up 44.5 per cent, chemical production up 52.1 per cent and metal production up 12.1 per cent.

The office said that while IIP is not the same as high growth rate, its rise indicates industry is remaining stable and sustainable throughout the economic difficulties.

Industrial businesses have striven to save costs by improving production technology and seeking new markets to retain their growth rate. — VNS
