I am not sure where you read a contradiction. There are no verified/confirmed reports of foreigners crossing the border at the points that I mentioned. These are local border crossings open only to local persons with proper permits. All reports of international travelers suggest that these crossings are not open to international travelers.
I don't think there are flights from Urumqi to western Mongolia.
There is a train from Urumqi to Almaty, Kazakhstan. There is a flight from Oksemen, Kazakhstan to Ulgit also called Olgii (Ust Kamenogorsk). You can obtain a Kazakh visa in Urumqi. Check with David B at stantour.com for information about the flight which is only once a week.
There is no border crossing in western China between China and Russia.
It would also be possible to travel from China to Kazakhstan to Russia to Mongolia and then across Mongolia and down to Beijing. The crossing from Russia to Mongolia is from Altai to Tsagaan Nuur in Bayan Ulgii province. There is no public transport across the border. There are no trains in this region.
The biggest potential problems with this plan would be obtaining the Russian visa and the Chinese visas. For a fee, the Russian visa can be obtained in Kazakhstan. Contact David B at stantour.com; he is based in Kazakhstan.
The Chinese visas will be more problematic. Currently China requires proof of transport into and out of the country which makes overland travel essentially impossible since train and bus tickets are almost impossible to obtain in advance.
