The West isn't vague. It is only semi-vague because, due to globalization, most cultures around the world have adopted Western norms of consumption, including China. Politically the West is Five Eyes with support of NATO. If push came to shove these would be the nations called upon to support a global conflict with China. Furthermore the hegemonic rule of the United States is a direct substitute to that of China. For every nation that China wants to exclude, overwhelm or subvert in its economic plans, the US will have an enemy or potential enemy of an enemy to ally with. Conversely if the US is separating economic ties with certain countries but building ties with others, it's this coalition that will operate against China as we move to our multi-polar world. There is a legacy of intellectual culture between Russia, the Mediterranean, and some of the Middle East with Western Europe – mainly due to Aristotle and his influence on the intellectual practice of all of the Abrahamic religions – but a lot of that complexity is screened off by the real military commitments extant between the nations in these geographic regions. Post WWII history is what scoped out the structure of the modern world, so post WWII history is what makes sense to use in our analysis of what the West will be in practice. As a proxy, English and the Romantic Languages as primary languages within a nation could be a decent heuristic of the what the West is culturally.
