Shares of Chinese tech giant Tencent plunged as much as 10% on Friday after US president Donald Trump issued executive orders against popular apps WeChat and TikTok.

Tencent pared losses through the session and closed roughly 5% lower. JSE-listed Naspers, which owns a 31% stake in Tencent via Prosus (-4% to R1,676.34), declined by 4% to R3,088.39 

The orders are set to bar US transactions with Tencent and ByteDance, which own WeChat and TikTok, respectively. The bans will take effect in 45 days and escalate tensions already lingering between the US and China.

The Trump administration alleges both companies track "vast swaths" of Americans' data and threaten their privacy from the Chinese government.

Tencent traded near record highs prior to the order. The company is among China's largest tech firms, and its Friday tumble dragged on peer firms. Xiaomi, ZTE, and Alibaba all traded lower through the session following Trump's order. The Hang Seng Tech index, which tracks the 30 largest tech companies listed in Hong Kong, closed 2.5% lower.

Trump first targeted TikTok in late July, calling on the company to sell its US unit or end operations in October. Microsoft confirmed on Sunday it was in talks to acquire the social media giant's operations in the US, Canada, Australia, and New Zealand. Trump has since demanded the Treasury Department take a cut from the deal, should it close.

Tensions between the economic superpowers flared earlier this summer after the White House ordered the closure of China's consulate in Houston. China fired back soon after, calling on the US to close its own consulate in Chengdu.

Hopes for a mild truce emerged earlier this week following reports that US and Chinese officials would meet in mid-August to discuss their "phase one" trade deal. Yet the Thursday executive orders mark a new front for the countries' shaky relationship.

Tencent closed at 527.50 Hong Kong dollars ($68.06) per share on Friday, up 41% year-to-date. Naspers gained 30% so far this year.
