Organised crime is becoming deep rooted in some regions of northeastern China, subverting economic growth and threatening social order, state media has warned. Outlook magazine, a Xinhua publication, warned in its latest issue of the 'serious consequences' of organised crime, highlighting one of many social ills that are breeding public discontent and undermining President Hu Jintao's pursuit of a 'harmonious socialist society'. Local authorities, especially in rural areas, often have close ties with triads and sometimes resort to the mafia-style use of intimidation and force during the acquisition of land and relocation of peasants for development projects. A national co-operative framework was urgently needed to crack down on organised crimes, with 4,028 being recorded across the country in the first nine months of this year. They involved more than 15,000 people, including 47 public officials, the magazine said. Heilongjiang province was a case in point, with more than 1,400 organised gangs having been smashed between 2000 and the first half of this year, it said. 'They used illegal means to prosper and gain social clout, which in turn helped them accumulate more wealth,' the magazine said. 'It's becoming a vicious circle and is seriously destabilising economic order.' Lian Baoshan , a triad boss in Harbin , Heilongjiang's capital, used force to beat off rival bidders in seizing housing development projects in the city, it said. Ironically, he began building his triad in the early 1990s, when China started setting up special agencies to prevent and control organised crime. His personal wealth had swollen to more than 10 million yuan since 1993. His gang's sway became so strong that it infiltrated the city's economic and legal sectors. The local police ran up against 'great difficulties' during their investigation because 'his friends were all over the local courts and police stations', according to the magazine. The central government has recently intensified its propaganda campaign to build 'social harmony', which means maintaining social order by pacifying the disgruntled poor who were left out of the country's economic boom. Xinhua reported yesterday that the country was considering introducing an inheritance tax as soon as possible to help narrow the growing gap between rich and poor. The increasing income disparity is among many factors, ranging from rampant corruption to widespread pollution, that have led to increasing social strife, a key concern of the stability-preoccupied Communist Party.
