1. Duh. But no one has vetoed any Russian or Chinese "positions" in the UN Security Council, though
both countries have vetoed attempts of other to get the UN to do something about Syria.
After vetoing other countries' proposals in the Security Council, if Russia or China wanted to make its position on Syria known via a counterproposal for action it could have put it forward . I don't know that anyone was trying to ignore the "positions of Russia and China", but it is hard to know what those "positions" are if you don't put them in writing and present them to the Security Council. Just saying "No" is not really a "position".
