Income distribution reform has once again come under the spotlight in China as observers pin high hopes on the upcoming key session of the Communist Party of China, scheduled to open on Saturday.

In February, the government unveiled a guideline for reforming income distribution mechanisms amid growing public concern over the widening wealth gap, though details on a timetable for the reform have yet to be made available.

"There's no doubt it's at the top of the agenda, considering the urgency of the issue," said Chi Fulin, president of the China Institute for Reform and Development, a Hainan-based think tank.
