From the UK website an interesting overview. Here is one passage:
One thing is clear though, the Gulf is no longer going to be an exclusively Western pond to operate in. There will be long term challenges about how to respond to the Chinese presence, both in the region, and realistically in time in the Med too. For the first time ever, we are on the cusp of an out of region power establishing a credible and sustainable military presence close to our strategic areas of interest.

I am aware that Oman's younger generation are less inclined to be pro-Western and PRC has made investments there that dwarf the UK's traditional role.
