    Then the novel coronavirus pandemic tore through the global economy.
    China shut down factories in January and February to prevent a larger outbreak and contain the virus, but at the same time it severely damaged employment and production domestically.
    Consequently, China's economy shrank by 6.8% in the first quarter of 2020 compared to a year earlier. For the first time in decades, Beijing didn't set a GDP target at its annual meeting of its rubber-stamp parliament, the National People's Congress (NPC), in May.

    Since then, China has been trying to dig itself out of its economic slump, and there are some signs of recovery — though the path forward is still looking slow and painful.
