China has experienced rapid economic growth in recent decades, with annual growth rates around 6-7%. This is due to economic reforms and opening up to foreign trade and investment, including joining the WTO. However, questions remain about whether China's high growth can be sustained long-term given potential weaknesses such as demographic changes, environmental problems, and overreliance on exports and infrastructure investment. A thorough analysis of China's strengths, weaknesses, opportunities, and threats would be needed to assess sustainability.
