The Brit needed one hour and 45 minutes to see off his French opponent, eventually prevailing 6-4 6-3 to set up a final showdown with Roberto Bautista Agut, who defeated number one seed Novak Djokovic in their semi-final encounter.
Murray is chasing his sixth ATP Tour title of the season, having also claimed overall glory at last weeks' China Open, while he can close the gap on Djokovic at the top of the world rankings to just 915 points if he secures victory in Sunday's final at Qizhong Forest Sports City Arena.
The 29-year-old admits that his main goal between now and the end of the season is to reach the top of the rankings for the first time in his career, although he concedes he still has work to do to surpass Djokovic.
"I said that I want to try to get to number one, but I'm still quite far away from [Djokovic], so I'm not thinking about the number one ranking this week or right now," he said.
The three-time major winner believes he is enjoying the most consistent season of his career to date which include claiming a third major title at Wimbledon in July, while he also reached the finals of both the Australian and French Opens.
Murray added: "I just want to finish this year as best as I can, it's been the most successful in my career.
"The last few months have been some of the most consistent I have been, so I just want to keep it going until the end of the year and finish as strong as possible."
