News of a suspected assassination attempt on former US President Donald Trump has sent China’s heavily censored social media into a frenzy, fueling conspiracy theories and mocking the US political landscape.

The Republican candidate was unharmed and a suspect was arrested after shots were fired Sunday in what the Federal Bureau of Investigation said appeared to be “an attempted murder” at Trump’s Florida golf course.

As the news spread to China on Monday, discussions about the incident were trending on the popular Chinese social media platform Weibo, with netizens pointing out that Trump had recently escaped an attempted assassination at a campaign rally on July 13.

“Again?” asked many commenters on the platform with more than half a billion monthly users.

Millions of people viewed the viral hashtag “Shooter was 500 yards from Trump,” leading to discussions about how Trump was lucky and had “a good fate.”

Palm Beach County Sheriff Ric Bradshaw said at a news conference Sunday that the shooter came within 300 to 500 yards of the politician.

Weibo quickly became a breeding ground for a number of conspiracy theories about the authenticity of the incident and the motives of those involved, with users hinting that the act benefited Trump in the polls. Other bizarre conspiracy theories spread on the platform, naming religious groups.

Apart from the conspiracy theories, there were many internet users who claimed that Trump would benefit from the incident.

Shen Yi, a professor at Fudan University’s Department of International Politics, said on his verified Weibo account that the story was “certainly not good news for Democrats. The potential favors Harris could have gotten through the presidential debate are negated.”

Three senior law enforcement officials told NBC News that the shooting suspect, Ryan Wesley Routh, was in the custody of the Secret Service. Details about Routh and his motives were still emerging.

Many posts on Weibo said the incident was an example of how unstable the US political system is and dominated by “terrorism and violence.”

“American democracy? There is no democracy in a country where the president is assassinated,” and “it’s safe to assume that assassinations of dissidents are just a common tactic,” one blogger with 1 million followers said in a post.

Shortly after the incident, Trump said in an email to a fundraiser that he was safe and in good spirits.

“There were gunshots in my neighborhood, but before the rumors get out of hand, I wanted you to hear this first: I AM SAFE AND WELL! Nothing will stop me. I WILL NEVER GUARD!” the email read.
