Xi Jinping said Wednesday the Communist Party of China (CPC) will strengthen oversight to ensure compliance with the Constitution, advance constitutionality review, and safeguard the authority of the Constitution.

Xi made the remarks while delivering a report at the opening session of the 19th CPC National Congress.

No organization or individual has the power to overstep the Constitution or the law, he said.

No one in a position of power is allowed in any way to override the law with his own orders, place his authority above the law, violate the law for personal gain, or abuse the law, he said.

"We must improve the Chinese socialist system of laws, at the heart of which is the Constitution," he said.
