BEIJING • Chinese cities had fewer "good air" days in the first half of this year compared with the same period last year, despite government efforts to curb incessant smog, according to official data.
China has vowed to target coal-burning and vehicle emissions, increase investment in clean energy and punish polluters in a bid to improve the air quality of the world's second-largest economy.
But the measures had yet to bear fruit in the six months of the year.
The Ministry of Environmental Protection's monitoring department said 338 cities reported "good" or "excellent" air quality on 74.1 per cent of days in the first half, down 2.6 percentage points from last year.

In Beijing and the surrounding area, the proportion of "good air" days fell 7.1 percentage points from last year to 50.7 per cent, while the density of hazardous particulate PM2.5 rose 14.3 per cent.
Residents in northern China were angered last winter after the country was smothered in severe smog. Schools and factories were temporarily closed, and cars were ordered off the roads.
"If (officials) turn a deaf ear or act indifferently, and the people, especially minors, are exposed to potential health risks, this is undoubtedly a dereliction of duty," Xinhua state news agency said at the time.
Xinhua reported yesterday that in the first half of the year, 610 million yuan (S$124 million) in fines were issued on environmental protection violations, up 131 per cent year on year.
Last month, China appointed a new Environment Minister, who promised a "protracted battle" to clean up the nation's notoriously polluted air, water and soil. Mr Li Ganjie took over the job from Mr Chen Jining, who was appointed acting mayor of Beijing in May.
Hebei province, which surrounds the capital, is expected to remain a key focus of Mr Li's work.
The heavily industrialised province is one of China's most polluted regions and is said to be the source of about a third of the particulate matter drifting over Beijing.
Chinese Premier Li Keqiang pledged cleaner air during his annual press conference in March, saying: "Blue skies should no longer be a luxury, nor will they be."
