Charlton have completed the signing of China captain Zheng Zhi on loan with a view to a permanent deal.
The 26-year-old, who plays in defence or midfield, joins from Shandong Luneng until the end of the season with Charlton having an option to buy him.
Zheng is the Addicks' first signing under the managerial tenure of Alan Pardew, who took over on Christmas Eve. Zheng enjoyed a brief trial at Charlton last month before heading to Qatar to represent China in the Asian Games.
The player scored 21 goals for Shandong Luneng as they won the national league title earlier this year.
