Last year, the U.S. company NanoRacks which "operates the only commercial laboratory in outer space", flew the first Chinese experiment to the ISS. On 21 February 2018, NanoRacks CEO Jeffrey Manber made a strong statement before the National Space Council:

... "Finally, as I look overseas, the United States cannot simply ignore China’s commercial space ambitions. China is quietly developing a robust commercial space industry. I say quietly because Americans are blinded by our own regulations, and mindset, from participation.

Large Chinese companies are creating commercial launch efforts while young Chinese entrepreneurs are raising funds from Silicon Valley to Hong Kong. On a governmental level, the European Space Agency has astronauts training to visit the planned Chinese space station. But the United States is barred. NanoRacks and others are limited on what we can sell in this marketplace.
 
Avoiding this emerging marketplace, albeit due to justified concerns over technology transfer and other legitimate challenges, is not the American global leadership that we strive to achieve.
 
Now, while my time today is brief, I urge us to negotiate a stern but fair agreement with China, and allow U.S. businesses to do what we do best: innovate and compete better than anyone else."
