It would be funny if China had the Hillary e-mails, since China did more US hacking than Russia, by an order of magnitude. The Chinese used to steal between $225 billion and $600 billion annually in intellectual property using various private and government sanctioned hacking methods. The Russians were small fries by that standard. Asking Russian to hack, is like asking the smallest kid to play center on your basketball team. That was the joke. Both the US and China were way ahead in that category.
The Russians did not have to clandestinely hack Hillary's server, since the Russians and Putin gave the Clinton Foundation $145 million. Even if we assume this was a legitimate donation, the Russian would have access to Hillary's server, via e-mail, to work out the deal and for payment transfer.
If Hillary open up any of Putin's email, the Russians are allowed in the server. An e-mail attachment is how virus get into a computer. After entry into the server, all the Russians had to do was linger in the server and observe in real time. This is the inside joke of Trump, that got the Clintons and Obamas to scramble.
The greed and arrogance of Hillary, made Hillary communicate with Putin, often, trying to get him to raise the donation, leading to her tossing out her common sense in terms of email entry. Then Bill and Barack had to scramble to clean up the mess.
Besides that, many US intel agencies also hacked the Hillary server. Many people in US government were aware of the server. The clandestine hacking was done to help protect Hillary from herself. These e-mails are out there on US government secure cloud backup.
