(CNN) -- China captain Zheng Zhi has come through a medical at Celtic and is set to sign a two-year deal with the Glasgow giants.
Zheng's all-action style was a favorite with fans during his spell at Charlton.
The 29-year-old utility player is a free agent after being released by English club Charlton Athletic, meaning the move does not have to be completed within the close season transfer window.
Zheng needs to obtain a work permit before he can be officially cleared to play for his new club in the Scottish Premier League, but manager Tony Mowbray is delighted to have landed a major target.
"Zheng Zhi is a player I have tracked for some time," he told Press Association.
"He is a highly-regarded player and was a thorn in our side when he played against us at West Bromwich Albion.
"I am delighted that he may join us. He will significantly add to the squad with his quality and the fact that he can play in a number of positions."
Zheng joined Charlton in December 2006 from Shandong Luneng, scoring nine goals in 63 games for the Addicks, who are now in the third flight of English football.
He has been linked with a number of English Premier League clubs, but has opted for Celtic, who are desperate to win back the Scottish title from arch-rivals Rangers.
Zheng will further boost Celtic's Asian contingent after last week's signing of promising young Korean Ki Sung-yong.
He has made 48 appearances for China, scoring 12 goals.
But UEFA confirmed that he will be ineligible for the group stages of the Europa Cup, having missed the signing deadline of midnight on Tuesday.
Celtic have made a good start to the Scottish league campaign, but were beaten 5-1 on aggregate by Arsenal in the final qualifying round for the Champions League.
