I can't really see an avoidance of the Opium Wars. The structural issues there are pretty insolvable, what with China sucking in speccie. The British are going to forcibly open the country for trade at some point. I think it more likely that Britain may preempt Japanese imperialism to the south instead. With more local readily available troops then the British are likely to get more greedy. We could well see a British Taiwan, and possibly British administered Shanghai etc.
Interesting. So could Japanese ambitions focus mainly on their North and West flanks? They could concentrate on pushing into Siberia and Manchuria against the Russians and Chinese.
