Shares of Chinese artificial intelligence firm SenseTime Group rose more than 4% from their issue price in early trading following their Thursday debut in Hong Kong. The stock later extended those gains and finished its first trading day in Hong Kong 7.27% above its issue price.

SenseTime has been caught in the crossfire of tensions between Beijing and Washington, with the firm earlier this month pushing its Hong Kong IPO back after being placed on a U.S. investment blacklist.
