Pasechnik told Christopher Davis that he had been approached by China to work for them. Instead MI6 helped him defect from Paris –where he was attending a science conference. He brought to Britain highly secret documents which showed how advanced the Russians were in bio-chemical weapons. The documents also contained evidence of China’s effort to become the world leader in the field.
MI6, the CIA, and the intelligence services of Canada, Australia and Europe are combining all their resources to establish if China has sent killer squads from its own secret service (CSIS) to murder all those scientists it had approached – and who had declined to work for China.
