How to supervise the exercise of power is a tough test for political parties all across the world. Those failing to solve the problem will fall into the historical cycle of rise and fall.

The Communist Party of China (CPC) is determined to face the challenge as it seeks to continue its successful rule.

The fourth plenary session of the 19th Central Commission for Discipline Inspection of the CPC, which opened in Beijing on Monday, has reaffirmed continuous efforts to promote full and strict governance of the Party as well as the resolve to supervise power and enforce discipline and laws.

The CPC's supervision system is unique in many aspects. One of the features is that intraparty oversight takes the leading role, while oversight by people's congresses, democratic oversight, administrative oversight, judicial oversight, auditing oversight, accounting oversight, statistics oversight, public oversight and oversight through public opinion are coordinated.

Party and state supervisory systems have been set up and improved so that power is exercised in a fair, law-based and clean manner.

With a comprehensive supervisory mechanism in place, it is equally important to implement it, effectively and precisely.

From January to November in 2019, disciplinary inspection and supervisory organs across the country filed and investigated 555,000 cases, with 485,000 people receiving disciplinary measures within the Party or government agencies. It is a strong signal that no one is above the law.

The CPC has stressed stepping up supervision regarding the tasks of securing a victory in building a moderately prosperous society in all respects and the battle against poverty. It will also crack down on disciplinary violations more severely in key areas, including the financial sector, state-owned enterprises, local government debt risks, medical institutions and overseas state-owned assets.

The CPC is a Marxist party with the unique advantage of strict discipline. The determination to limit power through the system and punish those violating discipline demonstrates the strength of the Party and has won the hearts of the people.

By governing itself strictly, the CPC becomes stronger. It is also contributing wisdom to the world about what is the true meaning of power, how to supervise the exercise of power, and how to use it for the people.
