A Chinese province near the Hong Kong border has ordered 150,000 police officers to launch anti-riot drills in warning protesters ahead of the country’s National Day on Oct. 1.

The Guandong Provincial Public Security Department ordered its troops to conduct more live-fire drills to improve their skills. The drills featured helicopters, naval vessels, and cutting-edge high-tech technology, according to the Daily Mail.

The ongoing pro-democracy unrest has lasted for more than 100 days, becoming one of the most sensitive and critical issues for the Communist Party in Mainland China.

Hong Kong activists has asked the United States for help, urging the U.S. Congress to take action against China over its crackdown on summer-long protests in the city.

Tens of thousands of protesters marched peacefully in Hong Kong with many holding banners that read, “President Trump, please liberate Hong Kong,” and “Re-Elect Donald Trump, Keep America great.”

They were welcomed on Capitol Hill on Sept. 18. The Hong Kong Human Rights & Democracy Act presented by Rep. Chris Smith (R-N.J.) is expected to pass since it has received bipartisan support.

“Today at a press conference hosted by @SpeakerPelosi—a bipartisan group of Democrat & Republican lawmakers vowed to move my bill—the Hong Kong Human Rights & Democracy Act (HR 3289),” Smith wrote in a tweet.

During the Victims of Communism Memorial Foundation (VOC) event, Sen. Ted Cruz (R-Texas) compared Hong Kong pro-democracy protesters’ efforts to defend their freedoms against China to former President Ronald Reagan’s efforts to tear down the Berlin Wall.

Cruz thanked the host of the event for “shedding a light on the darkness, the torture, the murder, and the oppression that communist regimes inflict on men, women, and children every day.”

“To the people of Hong Kong, America is with you. The people of the world are with you,” Cruz said. “Your freedom matters. Your courage is powerful, and it is inspirational.”
