According to the plan, China will formally set up a group of national parks and establish the new agency for natural asset management by 2020.

The new system will be scheduled to be improved to become more efficient by 2030.

Such national parks are expected to perform a larger role in ecological protection. They will comprise areas protected by the nature reserve system in China, according to the report delivered by Xi at the opening session of the congress on Wednesday.
