BEIJING, May 27 -- China is to improve its regulations on labeling genetically modified (GM) food to guarantee consumer rights.

The measure was included in a guideline issued by the State Council, the country's cabinet, to boost food safety, according to a government statement issued on Tuesday.

The guideline did not give details about the stricter rule to be implemented.

GM food remains controversial in China and consumers have complained it is hard to distinguish GM food from non-GM food due to poor labeling.
