On Nov. 12, 2020, President Donald Trump signed an executive order forbidding U.S. investors from investing in companies that he designated "Communist Chinese military companies." The ban takes effect at 9:30 a.m. on Jan. 11, 2021 and currently includes 31 companies listed here.

China's economy has expanded at a torrid pace in recent decades to become the world's second largest, as measured by nominal GDP. China, the world's most populous nation, has long been a manufacturing and exporting powerhouse. But the COVID-19 pandemic in 2020 has slashed China's growth in the short term. Despite this setback, an increasing number of Chinese companies are now available to U.S. investors. We look below at the 10 biggest Chinese companies by 12-month trailing (TTM) revenue. Unlike major U.S. companies, many Chinese companies on our list are either state-owned or are partly controlled by the state. The list is limited to companies that are publicly traded in the U.S. or Canada, either directly or through ADRs. Some foreign companies may report semiannually, and so may have longer lag times. All data provided by YCharts and as of September 9, 2020.
