Shares of Hong Kong-listedTencentplunged 5.04% on Friday, after U.S. President Donald Trumpissued executive orders targeting Chinese apps WeChat and TikTok.

WeChatis owned by Chinese tech giant Tencent, while short-video-sharing app TikTok's parent company ByteDance is based in Beijing.

Other Chinese technology companies were not spared, and many of them closed the trading day lower.

Shares of Semiconductor Manufacturing International Corporation in Hong Kong plunged 8.7%.Smartphone maker Xiaomi's stock fell 3.02%, while Hong Kong-listed shares of telecommunications firm ZTEdeclined 2.58%. Chinese tech juggernaut Alibaba also saw its shares in Hong Kong declining 3.04%.

The Hang Seng Tech index, whichtracks the 30 largest technology companies listed in Hong Kong that pass the screening criteria, also fell 2.51% to close at 7,386.66. In mainland China, the Nasdaq-style start-up board Chinext slipped 2.065% on the day to about 3,059.87.

Trump on Thursday issued executive orders banning any U.S. transactions with Chinese tech firms Tencent and ByteDance. The ban will take effectin 45 days andcould attract retaliation from Beijing.

The repercussions of Trump's order on Tencent may ring beyond just WeChat,China's most popular messaging app. The Chinese tech juggernaut is also a titan in the video gaming space, with stakes in companies such as Activision Blizzard and Riot Games (the firm behind "League of Legends").

The latest development comes as tensions between Beijing and Washington ratchet up, with both sides imposing retaliatory measures on each other, such as the closure of consulates in Houston stateside and the Chinese city of Chengdu.

U.S. Secretary of State Mike Pompeo said earlier this week that theTrump administration wants to see"untrusted" Chinese appslike WeChat and TikTok removed from U.S. app stores.

Pompeo detailed a new five-pronged "Clean Network" effort aimed at curbing potential national security risks and said because those apps have parent companies based in China, there were "significant threats to personal data of American citizens, not to mention tools for Chinese Communist Party content censorship."

Meanwhile, Microsoft is in talks with ByteDance to acquire TikTok's business in the U.S., Canada, Australia and New Zealand within the next three weeks, ahead of a Sept. 15 deadline.
