Interesting take by the Guardian on the divide between Williamson and the Treasury over the naval diplomacy approach toward China before his departure from government. Treasury seems to have the upper hand for now.
A Navy is only as capable as the politics behind it in various ways.
Its also driving the decision behind Huawei building UK infrastructure. Personally Id be surprised if Hammond survives the PM, so its possible we will see a realignment of principles when she has gone. We will see. Personally I think our foreign policy since 2010 has been overly monetarily obsessed. Not that you can live off principles, but we seem far to ready to jettison them to make ourselves appealing for the PRC. It makes me sick to see Tories behaving as Corbyn accolytes in this manner.
