LSE & PKU vs Imperial

I am lucky to have got offers for postgrad at both Imperial College and LSE & Peking University, but I can't decide which one to choose. I would love to hear some thoughts on these different degrees and which might be best for getting a job after.

The offers are:
Imperial: MSc Environmental Technology ( Global Environmental Change and Policy option )

LSE-PKU Double Degree in Environmental Policy, Technology and Health
- PKU: Master in Environmental Management
- LSE: MSC Environment and Development

A bit of background info:
I have an undergrad in International Development from a highly ranked university in this field. I have also done 2 years of Mandarin classes during this degree. I am going straight from my undergrad to postgrad and want to move into the environmental field. I am thinking of sustainable development, ESG or environmental policy. My undergrad was very theory-heavy and I would love to do a postgrad that's more technical and focus more on problem-solving.

As of now, the LSE-PKU would be one year at PKU and one year at LSE. However, the PKU year is bound to start this autumn, which means it would be fully online due to covid restrictions in China.
