A court in Zhuhai City in south China's Guangdong Province sentenced four drug dealers to death on Thursday.
Two were sentenced to death with a two-year reprieve, Zhuhai City's Intermediate People's Court announced.
Thirteen others from the same drug gang, which had sold about 5 kilograms of drugs including methamphetamine, were given life sentences or varying prison terms, the court said.
Hou Jingjing, a judge from the court, said more types of drugs were available on the black market, and more people were getting involved in drugs.
On the same day in Beijing, a 22-year-old man was sentenced to death with two-year probation for transporting 2 kilograms of methamphetamine.
The young man was caught at a Beijing railway station in Nov. 2015 after alighting a train from Guangdong.
On Wednesday in Xuzhou City in east China's Jiangsu Province, three out of eight members of a drug gang were sentenced to death.
It was the biggest drug case ever seen in Xuzhou, involving more than 29 kilograms of methamphetamine and ketamine, the city's intermediate people's court said.
