Trump seems to be the the first US president to go against the one china policy and wants to start a trade war with china.
China already said it will answer accordingly with economical and military means.

In the case china allies with russia - which is highly likely based on geo-strategical positions  - what are the chances that trump will be succesful?

There are stories of china talking indirectly with trump through jack ma who promised to create 1 million jobs in the US in the next coming 4-8 years, but isnt this more or less just a drop of water on a hot stone?
