Chinese Premier Li Keqiang said it is “very difficult” for China’s economy to grow at a rate of 6% or more because of the high base from which it was starting and the complicated international backdrop.

The world’s No.2 economy faced “certain downward pressure” due to slowing global growth as well as the rise of protectionism and unilateralism, Li said in.

China’s gross domestic product (GDP) grew 6.3% in the first half of the year, and Li said the economy was “generally stable” in the first eight months of the year.

“For China to maintain growth of 6% or more is very difficult against the current backdrop of a complicated international situation and a relatively high base, and this rate is at the forefront of the world’s leading economies,” Li was quoted as saying.

Analysts say China’s economic growth has likely cooled further this quarter from a near 30-year low of 6.2% in April-June.
