According to the latest trove of messages uncovered by the New York Post from what is said to be Hunter's personal laptop, the son of the Democratic presidential nominee communicated with China's largest private energy company, CEFC.
The latest emails, published again early in the morning, focus on Hunter's dealings with Ye Jianming, the former chairman of CEFC in 2017.
Ye has not been seen since being taken into custody by Chinese authorities in 2018 amid rumored links to the Chinese military and intelligence services.
CEFC went bankrupt earlier this year after it was unable to repay its debts after warnings over its lack of transparency and dealings with sanctioned Russian firms.
In one email sent to Hunter in May 2017 titled 'Expectations', details of 'remuneration packages' for six people in a business venture were discussed.
He was identified as the 'chair/vice chair depending on agreement with CEFC'.
Another email outlines a 'provisional agreement' where 80 per cent of the 'equity' would be shared equally among four people.
The email divides the equity into '20 H' - meaning 20 per cent equity to Hunter; 20 per cent to RW, meaning Rob Walker, also of the jc2r consultancy; 20 per cent to another man called Tony Bubulinski.
The remaining 20 per cent was split with 10 per cent going to 'Jim' who is otherwise unnamed, and then '10 held by H for the big guy?' The “big guy” is unnamed.
In another 2017 email, Hunted reportedly discussed a deal with Ye. According to the leaked emails, Biden wrote that Ye had been influential in improving a three-year consulting contract with CEFC that would pay him $10million annually just for introductions.
He was given half ownership of a holding company, with Ye owning the other half.
Biden allegedly wrote: 'Consulting fees is one piece of our income stream but the reason this proposal by the chairman was so much more interesting to me and my family is that we would also be partners inn the equity and profits of the JV's [joint venture's] investments.'
A photo from August 2017 appears to show a flowchart of the ownership of Hudson West which is split equally between Hunter Biden and 'Chairman'.
A report on Biden's business dealings released last month found Hudson West III opened a line of credit, coincidentally, in September 2017.
Also seen in the emails was an agreement from one of Ye's associates to pay Biden a retainer of $1million for counsel on US law.
Said offer was made by former Hong Kong government official Chi Ping Patrick Ho, who has been convicted in Manhattan for two schemes to pay $3million in bribes to African government officials for oil rights.
