For all the war trump beat, China very calculated the main objective for war against any nation, China won't fight a war when long term objectives never meet the outcome of the war prediction. Remember China fought Soviet Union at the height of Soviet Union empire to stop Soviet advancing deep inside China territory.If Bhutan is on the same page with China. China can open a case against India at the UNSC.
And the big thing?
Russian Veto would be missing.
May be the RAFALE veto, only probability.
