Global confusionism!
But the summit could also be helped by each party bringing forward mutually helpful proposals. For instance China had a business model based on lending the US money so that it could buy from them which thereby creates jobs the Chinese. And, as so many business models do, it did fine until, in this case until the US could not afford to take on much more debt. What now? If they do not lend the US more money, Chinese could lose their jobs and China could lose a lot on their actual dollar loans to the US.
It might therefore be time for a US public-debt to Chinese jobs conversion plan. In it millions of Chinese workers would pay 10% of their gross Chinese salaries to the US in order to retain an access to the US markets. At a Chinese salary of 500 dollar per month, to repay this way the current 1 trillion dollars of outstanding US debts to China (no interests), that should take only about 10 year, for only about 167 millions of Chinese.
