China's top legislature, along with other authorities, convened on Thursday to study President Xi Jinping's latest anti-corruption instructions.

Xi delivered a speech to the fifth plenary session of the 18th Communist Party of China's (CPC) Central Commission for Discipline Inspection (CCDI) on Tuesday, stressing adherence to party rules and calling for continued corruption eradication efforts.

The National People's Congress (NPC) Standing Committee told all legislators that they must follow Xi's instructions and strictly adhere to party discipline to fulfill their Constitutional duties.

The meeting was presided over by Zhang Dejiang, chairman of the NPC Standing Committee.

At a meeting of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), China's top political advisory body, advisors were told the implementation of Xi's instructions was an "important political task".

They must be self-disciplined and safeguard unity within the party and follow the central authorities, led by Xi, according to the meeting, which was presided over by Yu Zhengsheng, chairman of the CPPCC National Committee.

The Supreme People's Court and Supreme People's Procuratorate also held meetings to study the president's speech, both vowing relentless punishment of corrupt officials.
