"These satellites may be used in furtherance of Chinese military goals and technological development, raising significant national security concerns for the United States," the said.
The letter by the Senators to Pompeo came following a report in the Wall Street Journal early this year, saying Boeing has built nine satellites and is in the process of building another for sale to China.
The Senators also said the communications satellites may also be used in support of domestic efforts to suppress protests and the free exercise of religion among other human rights.
Grassley and Ernest also sought the department's assessment of whether these sales constitute a violation of the broad statutory prohibitions on selling satellite technology to China.
They demanded information on how to prevent circumvention of those export control laws and how to stop further transfer of American-built satellites that may be used to support human rights abuses and Chinese military development.
Chinese companies using American-made satellites also raises serious military concerns since these satellites are used for more than commercial communication.Commercial satellites can be deployed for military purposes such as imaging an adversary's military installations for intelligence, surveillance, and reconnaissance (ISR) purposes, they said.
They asked how could US ensure that China does not obtain further access to the use of American-built satellites against the religious minorities.
"How can we ensure that China does not obtain further access to or use of American-built satellites or other regulated technology to support its oppression and subjugation of religious and ethnic minorities, including the internment of the Uyghur population? the Senators asked in the letter.
