The number of motions introduced by deputies to China's top legislature has risen this year, and they've focused heavily on economics and the environment, the secretarial department of the National People's Congress said.

By noon on Tuesday, the deadline for motions, the department had received 522 motions, 54 more than last year, said Guo Zhenhua, deputy head of the department's proposal group.

Of those, more than 90 percent had to do with the country's major legislative initiatives, including economic and judicial reform, Guo said.
