Not really, not in the terms that matter, ready access to oil not controlled by rivals. China has offered quite a lot of loans to Venezuela, secured in oil. Venezuelan oil production is, for whatever reason you want to blame, far below the Chavez days.
It's almost certain that China won't defend Venezuela by force out of pure ideology, they aren't the Soviets in that regard for damn sure, and they don't seem inclined to believe they'll recoup their investments under Maduro.
Short of Venezuela selling their sovereignty and putting Chinese bases everywhere to defend Chinese-managed oil production I'm not sure what they can offer for protection.
As for Russian guarantees...
Lol
Tl;Dr the rambling nonsense,
It's not in their interests for America to conquer more oil reserves, but Venezuela isn't offering enough incentives (sweet tasty oil) on their own to actually be worth stopping it either.
Also it's all a very thinly disguised recruiting video for the Japanese Defense Force but you're probably not a Japanese child being brainwashed so... Anime waifus?
