China moved to tighten controls over two chemicals that can be used to make fentanyl, in an apparent olive branch to the US that may help maintain their fragile trade truce.
Authorities added two previously unclassified precursors to a list of Class Two chemicals, according to a joint statement by six government departments on Monday. The label will subject the substances, 4-piperidone and 1-boc-4-piperidone, to tougher supervision starting July 20.
