According to the Russian Government and Ministry of Foreign Affairs Official Website, there is only one record of Dmitry Medvedev's meeting with Xi Jinping in 2015. There is no record of Putin attending the 2014 Nov 11 APEC meeting as well as meeting with Xi Jinping on May 9, 2015.
Putin didn't meet with Xi Jinping because he knew that it was the clone of Xi Jinping who visit Russia.
Besides, no record of Great Harlot Peng Liyuan attending the 2014 APEC and the 2015 Masco Victory Day Parade can be found in 《Peng Liyuan Activities Log》！
Those videos on YouTube are certainly fake and were made by computer technology. They used human cloning masks to impersonate Xi Jinping and Putin.
