Pledge to uphold Constitution will be required of leaders

Revising China's Constitution is an important task for national legislators in this year's two sessions, but the fundamental law will also take on new prominence for the nation's leaders, as they will pledge allegiance to the Constitution.

It's the first time that's been required, said Zhang Yesui, spokesman for the first session of the 13th National People's Congress.

"The Constitution, which reflects the common will of the Communist Party of China and Chinese people, is the country's fundamental law and the general outline for governing the country well and ensuring national security," Zhang said at a news conference on Sunday.
