There are a total of 18 professional think tanks under the Chinese Academy of Social Sciences (CASS), president of the academy Wang Weiguang has said.

Wang made the remarks at an international forum on Chinese philosophy and social sciences held in Beijing Friday, saying that the academy is dedicated to fostering national high-end think tanks with extensive influence both at home and abroad.

The tanks primarily focus on Marxism, economics and finance, social culture, international relations and border areas, according to the academy.

As this year marks its 40th anniversary, Wang said the academy has become a prestigious institute in the study of philosophy and social sciences in China.

By the end of 2016, the academy has completed almost 13,000 monographs, over 147,000 papers and more than 27,000 research reports, Wang said.

The CASS also has over 160 cooperation agreements with academies, think tanks, international organizations or higher education institutes in more than 100 countries or regions.

A large group of milu Deer have been spotted in central China’s Hunan Province, authorities said.

Staff with Hunan Provincial Forestry Department found 62 wild milu deer during a drone inspection in a state nature reserve near Dongting Lake, the second-largest freshwater lake in China. It is the biggest group of wild milu deer ever seen in the area.

Staff with the department found the deer foraging during a survey on Thursday.

Last year, authorities found 41 of the deer in the reserve.

“The extra deer spotted this year must be the calves,” said Zhang Hong, an official with the administration of the nature reserve.

Milu, also known as Pere David’s deer, is a species endemic to China, but overhunting and loss of habitat led to its near extinction in the early 20th Century.

In 1986, the British government gifted 39 milu deer to Dafeng Milu National Nature Reserve in east China’s Jiangsu Province, starting a revival of the population in its homeland.

Forty five people were sentenced in Shenzhen on Friday afternoon for their parts in a landslide that left 73 dead and four others missing in December 2015.

The suspects, mostly from Hong Ao landfill, the Yixianglong company which managed the dump site and local governments were tried in the Intermediate People’s Court of Shenzhen, the People’s Court of Nanshan district and the People’s Court of Bao’an district from April 26 through 28.

Long Renfu, boss of Shenzhen Yixianglong, was sentenced to 20 years in prison and fined 10 million yuan (about 1.5 million U.S. dollars) for bribery and negligence which led to the accident.

The dump site had a planned storage of four million cubic meters and a maximum stack height of 95 meters, but when the accident happened, its actual storage reached 5.83 million cubic meters and the waste heaps stood as high as 160 meters.

Meng Jinghang, former head of the city administration bureau of Shenzhen, was convicted of abuse of power and taking bribes of 24.9 million yuan and 800,000 Hong Kong dollars. He was sentenced to 20 years of imprisonment and fined eight million yuan.

Peng Shuiqing, former head of the Guangming New District management bureau of the Urban Planning, Land and Resources Commission of Shenzhen, was sentenced to 16 years and fined one million yuan for the same offences.

Another 17 government officials were sentenced to three to seven years in jail for negligence and abuses of power. Another 25 also received penalties.

The landslide occurred when a huge waste pile collapsed. The accident resulted in a direct economic loss of 880 million yuan, and was believed to be caused by mismanagement rather than any geological reasons.
