President Donald Trump is losing to China on the world stage, according to economist Paul Krugman.

Krugman referenced a new column by New York Times columnist David Brooks, which argued that, “China is a grave economic, technological and intellectual threat to the United States and the world order.”

“If China is an existential threat to the liberal international order, do we have the capacity to improve our system so it can face the challenge — to invest in human capital, to reform our institutions, repair the social fabric and make our political system function once again?” Brooks wondered.

Krugman then explained how Trump was making the situation even worse with his investment priorities.

Think about what our investment choices say about us. China's big investment project is Belt and Road — which isn't just about building productive infrastructure, but about reaching out to spread its influence in the world 2/ https://t.co/0M0Ku4fCe1

Meanwhile, we're doing less and less public investment 3/ pic.twitter.com/mPo4eUlJFS

As some of us predicted, Trump has done nothing whatsoever to move on his infrastructure promises 4/ https://t.co/alnlqhhbcF

And the only thing he's actually trying to build – is willing to trash the Constitution to build – is a wall that, aside from being useless, symbolizes America's fear of the outside world and our desire to cower inside our borders. 5/

The wall obsession should really be seen as evidence of America in decline. Trump is doing all he can to make us weak again. 6/
