"But if it is tariffs on goods coming into the country, the Chinese aren't paying", he said, eventually eliciting a "No" from Kudlow.
Trade talks as Washington demanded promises of concrete changes to Chinese law and Beijing said it would not swallow any "bitter fruit" that harmed its interests.
U.S. benchmark 10-year Treasury note yields inched down to 2.439pc, partly as a safe haven but also on speculation that the escalating trade war would put more pressure on global growth and thus keep major central banks accommodative.
"The perception that China can not bear it is a fantasy and misjudgment", the commentary said.
"If they weren't being seriously provoked, the Chinese people would not favour any trade war".
In the face of Washington's move, China has repeatedly stressed that slapping additional tariffs is no solution, and the only way forward is cooperation and consultation based on respect for each other's core concerns.
A year ago the U.S. imposed a 10% tariff on $200bn worth of Chinese products - including fish, handbags, clothing and footwear. "They LOVE ripping off America!", Trump said. These often pass on the costs to customers, mostly manufacturers and consumers in the United States.
"The risk of a full-blown trade war has materially increased, even though both sides seem to still want a trade deal and talks are expected to continue", UBS economist Tao Wang said.
"We were moving well, constructive talks and I still think that's the case", Kudlow said.
But he also assured that because the U.S. economy "is in a boom", it would not be damaged "in any appreciable way" by the tariffs.
Mr Kudlow had admitted that more talks were planned while also stating that Trump and China's Xi Jinping would "meet in Japan at the G20" summit at the end of June.

While he noted that tariffs should be on the table as part of a "comprehensive strategy", like Ms. Harris, Mr. Moulton argued the US needs to coordinate with allies to contain China's growth. China had previously imposed taxes on $110 billion of American products, but has not said how it might retaliate against Trump's latest increase in tariffs.
On Friday, the Trump administration raised duties on $200 billion of Chinese imports to 25% from 10%, after charging that China had backtracked on commitments it made earlier in the talks.
US farmers, a key constituency of Trump, have been among the hardest hit in the trade war, with soybean shipments to China dropping to a 16-year low in 2018.
