Two Chinese drug dealers were executed by lethal injection Tuesday in Nanjing, the capital of east China's Jiangsu province.

One of the criminals, Cao Yi, 36, from Chongqing municipality in southwest China, was first detected in May 2001. Cao, who sold heroin, had made more than 1.8 million yuan (about 220,000 US dollars) by dealing more than 10 kilograms of heroin between Chongqing and Nanjing in June 2002.

The other convict, 35-year-old Ma Jun, from northwest China's Xinjiang Uygur autonomous region, was arrested for dealing heroin on June 22, 2003. He was accused for buying 880 grams of heroin twice from May 16 to June 5 in 2003.

The police also found 854 grams of heroin at his rented house.
