谢邀答。从句义和表述逻辑来看,显然应该理解为非限制性定语,是对restrictions的一个补充性说明。
请问这里的 focusing…后的部分是作为 more targeted restrictions 的非限定性定语还是作为 the financial hub 的伴随状语呢?
Over the past two years, the financial hub, with a local economy of over $660 billion in 2021, had tried to avoid a blanket lockdown and instead relied on more targeted restrictions, focusing on shops or buildings where infections were found.
