Chen condemned the human rights record of the Chinese Communist Party (CCP) on Wednesday.
"In China, expressing beliefs or ideas not approved by the CCP--religion, democracy, human rights--can lead to prison," he said. "The nation lives under mass surveillance and censorship."
Vice President Mike Pence delivered the keynote address of Wednesday evening, where he officially accepted the party's nomination to run for vice president in 2020.
In a lengthy speech where he focused on foreign policy, the economy, and domestic law enforcement, Pence touted the administration's record supporting the right to life and school choice.
"President Trump has stood without apology for the sanctity of human life, every day of this administration. Joe Biden, he supports taxpayer funding of abortion right up to the moment of birth," Pence said.
Other convention speakers on Wednesday evening included Richard Grenell, Trump's former Acting Director of National Intelligence and member of the Log Cabin Republicans, a group which represents conservatives and Republicans identifying as LGBT.
Grenell recently endorsed Trump in a video where he called the president "the most pro-gay president in American history." Trump tweeted in response "My great honor!!!"
Former University of Notre Dame football coach Lou Holtz, a Catholic, also endorsed Trump on Wednesday evening for his pro-life stances and support for prison reform and school choice.
"The Biden-Harris ticket is the most radically pro-abortion campaign in history. They and other politicians are 'Catholics in Name Only' and abandon innocent lives," Holtz charged. "President Trump protects those lives."
One mother of a child with Down Syndrome spoke about school choice on Wednesday, after she shared her story of having her child Samuel.
