Shares of Dongfeng Motor Group surged 69.2 percent in Hong Kong as they resumed trade on Monday, after the company's parent said on Friday it planned to take the automaker private at a premium.

The stock opened at HK$10.10 per share, the highest since November 2017, before trimming gains later to trade at HK$9.47, still up 59.1 percent. It was the biggest percentage gainer on the Hang Seng Automotive Index, which rose 1.7 percent.

Dongfeng Motor Corp, the mainland state-owned parent, said it would take Dongfeng Motor Group private in a deal valued at HK$55.13 billion while separately listing its electric vehicle arm, Voyah, in Hong Kong.

Under the deal, Dongfeng Motor Corp will pay HK$6.68 per share, representing an 11.9 percent premium to Dongfeng Motor Group's last close on August 8 before trading on the stock was halted.
