What is the subject of "in line with……" in this sentence?
"There have been signs in recent months that Xi Jinping and his colleagues have decided to toughen their stance on Taiwan in line with their broader attempt to impose conformity and centralisation and to impose order on China’s peripheral regions of Xinjiang and Tibet."
1. What is in line with their broader attempt to impose conformity and centralisation? "The decision to toughen their stance on Taiwan" or "their stance on Taiwan"?
2. Can I restructure the sentence in this way: In line with their broader attempt to impose conformity and centralisation, Xi Jinping and his colleagues have decided to toughen their stance on Taiwan.
Thanks.
