But still, it's not anywhere near excessive!
So far, due to the effects of the pandemic, China's economic losses alone have exceeded 50 billion US dollars. It is foreseeable that if the NDM-EH cannot be resolved quickly, economic losses will continue to rise rapidly.
Thus, if a mere 10 billion dollars can curb such massive losses and stabilize the political environment, it is not only not too much, it's pitifully inadequate. It's a very cost-effective deal.
The Chinese government, of course aware of this, signed several other policy greenlight agreements privately after signing the licensing agreement.
In summary, following Chen Yang's instructions, Feng Li made some compromises and did not play any tricks on the agreement, which won the goodwill of the Chinese government.
