A few points about Jochi Khan, Kazakhs, and Mongolian chauvinism:

Recently, the Kazakh government has erected this statue of Jochi Khan, son(?) of Chinggis Khan and forefather of the Golden Horde, near his supposed mausoleum, and Mongols have taken to twitter to express their disapproval of kazakhs "co-opting" Mongolian identity for themselves.

There is a chauvinistic thread in many Mongolians' views on their country, considering themselves the masculine traditional conquerors of the world surrounded by weak effeminate nations seeking to steal their glory for themselves, and Kazakhs are included as one of those.

The population of mainland Mongolia is predominantly Khalkha, a Mongolic ethnic group that considers themselves the direct descendants of the Mongol empire. They look down on other non-Chinggisid mongolic groups like Buryats, Oirats and Kalmyks for not being "pure mongols."

Kazakhs also draw the ire of Khalkhas, considered a Muslim Turkic ethnic group that tries to steal Chinggisid glory away from the Khalkas. Khalkhas also stereotype kazakhs as being effeminate and gay due to Kazakhstan being a lot more developed and modernized than Mongolia.

Khalkhas believe they have a monopoly on "trad steppe nomad life," a fact they flaunt to foreign tourists to get them to come to Mongolia, and don't appreciate it when Kazakhstan tries to do the same. (Ironically, they show Kazakh eagle hunters as "mongolian" for tourism).

Such sentiments actually have deeper roots than most people realize, going as far back as Chinggis Khan's early life, before he was the founder of the great Mongol empire.

Before he was called Chinngis Khan, Temujin's wife Borte was kidnapped by a tribe called the Merkits. When Borte was recovered, she was found to either be pregnant or had already given birth to a son, who was named Jochi, meaning "guest."
