A key storyline of President Joe Biden’s overseas trip was how different Biden was from President Donald Trump, and indeed he was — except in one crucial area.

Biden’s hawkishness on China was a reflection of how Trump changed our posture toward Beijing.

It is the ultimate victory for a politician if he doesn’t just reorient his own party, but the other party — Ronald Reagan and Margaret Thatcher both did this

On China, Trump’s wrenching shift in the U.S. approach is now getting the tribute of broad acceptance by a successor who has nothing good to say about him and wants, in fact, to differentiate himself from the former president as much as possible.

It is impossible to imagine President Barack Obama pressuring reluctant European allies to take a tougher line on China, as Biden did over the past week.

For 20 years, the U.S. had operated on the bipartisan assumption that welcoming Beijing into the international system and establishing closer commercial ties would pay off.

By the end of the Obama years, it was increasingly clear that this strategy had come a cropper.

The Obama team talked of a “pivot to Asia,” or shifting attention and resources from the Middle East to Asia, but this was more sloganeering than substance.

Even as China invested massively in its military, encroached further on the South China Sea, continued to engage in cyber espionage and hacking, launched the Belt and Road Initiative, started to build its own international financial architecture via the Asian Infrastructure Investment Bank, and began its campaign of cultural genocide against the Uyghurs, Obama remained accommodating.

The old consensus on China had become unsustainable, but it took Trump to demolish it.

For years, the security and trade relationships with China had been considered separate realms, or worse, we’d been afraid of pushing too hard. Trump linked trade and security, and sent the message to the world that the co-mingling of U.S. and Chinese economies wasn’t inevitable and, indeed, could be reversed.

Trump over-personalized his relationship with President Xi and oversold what might come of the trade war with China, but the reorientation was unmistakable.

Beneath the drumbeat of controversy from the top, though, Trump officials undertook a thoughtful, deliberate effort to set out and implement a new strategy.

The administration produced several important documents across the government that crystallized the new thinking.

The administration worked to buttress alliances in Asia and successfully lobbied European countries to exclude Huawei from its networks.

By any fair measure, this was a serious campaign and China’s behavior in recent years has only underlined its necessity.

It would be foolish to trash all of this only because it had the name “Trump” attached to it. To his credit, Biden hasn’t.

Biden’s bonhomie with Emmanuel Macron and Angela Merkel was fine as far as it went, and a marked difference from Trump. But, more importantly, his emphasis on what might be the defining confrontation of the first half of the 21st century made an implicit nod to the enduring strategic transformation brought about by his predecessor.
