China has released new guidelines on the civilian unmanned aerial vehicle (UAV) industry, expecting the market value of the industry to rose 40 percent year on year on average to 60 billion yuan (about US$9.1 billion) by 2020.

The market value would be tripled to 180 billion yuan by 2025, according to the guidelines made by the Ministry of Industry and Information Technology.

The estimate was much higher than a forecast by an iResearch report last year, which said the overall market of UAVs, commonly known as drones, could reach 75 billion yuan by 2025 in China.

The country's UAV manufacturing industry has been expanding rapidly in recent years thanks to extensive use of drones in fields such as surveying and mapping as well as rising individual consumption.

The ministry said China is playing a leading role worldwide in consumer UAV product manufacturing.

In the future, the ministry will promote national unified management of the industry, strengthen its competitive edge and help foster several leading drone manufacturers by 2020, according to the guidelines.

While it is good to see drones increasingly used in agriculture, environmental monitoring and public entertainment, civilian drones have threatened the safety of civil aviation on many occasions.

In late April, four drones flown illegally over Chengdu Shuangliu International Airport in southwest China's Sichuan Province. They obliged 58 flights to land at alternative airports, four to return, and many more to be canceled.

China requires civilian drones weighing more than 250 grams to be registered under real names from June 1 to improve civil aviation safety. Registration of civilian drones is a common international practice.
