The People’s Liberation Army has released a video of a recent exercise employing the advanced DF-16 medium-range ballistic missile, a weapon seen as filling a gap in the nation’s arsenal.

Several launch vehicles carrying the ballistic missiles were seen in the footage that the PLA published on its video website, released to show the training of Rocket Force missile brigade soldiers around the Spring Festival holiday.

The participating units handled a number of scenarios, including chemical/biological contamination, countering satellite reconnaissance and electronic jamming. The crews practiced multiple maneuvers, such as rapid loading, redeployment and launch sequence, though the video showed no missile actually being launched.

Two types of DF-16 that appeared in the exercise are the bullet-shaped missile that is considered the original DF-16 and a new variant that features a maneuverable warhead and several extra fins.

The video represents the third time the DF-16 has been shown to the public. The missile made its debut at a military parade in Beijing in September 2015. In July, a television news program showed General Fan Changlong, a vice-chairman of the Central Military Commission, inspecting a DF-16 unit of the Southern Theater Command.

Though the PLA has never disclosed its ballistic missiles’ specifications, experts said the DF-16 poses a challenge to foreign military installations along the first island chain, which is what the Chinese military calls the series of islands that stretch from Japan in the north to China’s Taiwan and the Philippines to the south.

Xu Guangyu, a retired major general and now a strategy researcher, said that DF-16 has a strike range of more than 1,000 kilometers, filling the gap that previously existed with the absence of a medium-range ballistic missile in the PLA’s arsenal. He said the missile also is able to reach Okinawa, a Japanese island about 400 km from China’s Diaoyu Islands.

Shi Hong, executive editor of Shipborne Weapons, said the DF-16 was developed by China Aerospace Science and Industry Corp based on the DF-11 short-range ballistic missile and can carry a warhead of at least 500 kg. The missile has a strike accuracy as good as that of a cruise missile, Shi said. It is also able to maneuver in its final stage to penetrate enemy defensive firepower, he said.

Other PLA Rocket Force brigades also mobilized their DF-11, DF-15 and DF-21C ballistic missiles during training around Spring Festival, according to PLA media outlets.

In another development, Washington Free Beacon, a news website in the United States that specializes in military affairs, reported on Jan 31 that China conducted the first flight of the DF-5C intercontinental ballistic missile in January. The missile carries 10 multiple independently targetable re-entry vehicles. The DF-5C is the latest variant of the three-decade-old DF-5 family, the report said.

An unidentified officer from the Defense Ministry’s Information Bureau reached by Shenzhen TV on Saturday would neither confirm nor deny the DF-5C test, but said such tests are not aimed at any foreign nation or specific target.

Drones have been found at the clearance protection zone of an airport in southwest China’s Yunnan Province, and local police are investigating.

Sources with Kunming Changshui International Airport in the provincial capital said Sunday that there were four or five incidents in the past two days of drones flying close to the airport.

“Regulations stipulate that unmanned balloons, kites, gliders and parachutes are not allowed within the clearance protection zone, about 1,028 square kilometers surrounding the runway,” an official said. “Those who violate the regulations are subject to fines up to 100,000 yuan (about 14,600 U.S. dollars).”

The flying of drones could pose a threat to aviation safety, though the incidents reported did not disrupt flights at the airport.

The Ministry of Culture has agreed to build an experiment zone in China’s northwestern Qinghai Province to protect Tibetan ecological and cultural heritage.

According to Wang Dongmei, head of the culture and sports bureau in the Yushu Tibetan Autonomous Prefecture in Qinghai, the zone will cover the city of Yushu and its adjacent counties.

On the zone’s protection list are the physical and cultural heritage items related to the local Tibetan people in the Sanjiangyuan area, which is home to the headwaters of the Yangtze, Yellow, and Lancang (Mekong) rivers, Wang said.

Yushu is home to seven national-level cultural heritage sites, 29 provincial-level sites as well as two historical villages. The song and dance, costumes of ethnic minorities, and metal forging techniques are all listed as intangible heritage in China.

Wang told Xinhua that Yushu has eleven national items of intangible heritage and 24 national “cultural inheritors.”

“The experiment zone will help boost protection of Tibetan culture and local ecology as a whole, and sustainable development of the society and economy,” said Tsering Teg, governor of Yushu.

Yushu has recovered from a magnitude 7.1 earthquake that hit the region on April 14, 2010. It affected 246,800 people, leaving 2,220 dead and more than 100,000 homeless.

China’s Supreme People’s Procuratorate (SPP) has promised severe punishments for economic crimes that affect interests of lots of people, including illegally absorbing public deposits and fundraising fraud.

It also urged procuratorates to give more priority to the prevention of financial risks, cracking down on crimes such as money laundering and underground banking, and take an active part in Internet financial risk management, according to an SPP statement.

The SPP also pledged to strengthen work against manipulation and insider trading in securities and futures markets, and in supervision of property markets.

High-profile cases of financial crimes have been reported in China in the past years, including the illegal fund-raising activity of Ezubao and the case of Xu Xiang, general manager of a Shanghai-based investment company indicted for allegedly manipulating the securities market.

In 2016, 304 department-level officials from central government bodies received disciplinary punishment, according to disciplinary authorities.

Among the 304 officials, 126 were punished for violating the “eight-point” guidelines against bureaucracy and extravagance, according to a work conference on disciplinary work of central government bodies.

In 2016, discipline inspection authorities dealt with over 22,500 tip-offs concerning disciplinary violations of central state agencies’ officials, four times that of the previous year.
