Can you imagine if he made changes at the last minute with Obama or Kerry? They would bend over backwards trying to accommodate him, like they did Iran. Trump told him to take a hike. Xi will negotiate with more respect next time.
From the NY Times:
"BEIJING — China’s leader, Xi Jinping, seemed confident three weeks ago that a yearlong trade war with the United States could soon subside, handing him a potent political victory.
He even made a speech saying China would protect intellectual property, encourage foreign investment, and buy more goods and services from abroad — all changes the United States had been demanding as the countries tried to negotiate a deal.
But just a week after that speech, Chinese negotiators sent the Americans a substantially rewritten draft agreement, prompting President Trump to accuse Beijing of reneging on terms that had been settled.
...
Having apparently made that decision, it is clear that Mr. Xi misjudged Mr. Trump’s eagerness for a deal and how far he could push the American negotiators, according to more than a dozen people, including current and former officials, researchers, lawyers, and trade experts familiar with the deal and how it fell apart.
