No.
The US executive branch didn't decide that. The machine decided that, during the Obama Administration (not Obama's decision either), and they have been thinking about - plotting about - this confrontation as far back as the early 1990s at least. Four-star general Wesley Clark talked publicly about that the Pentagon has been expecting to have to confront China for ~25+ years.
There are countless article you can dig up on this, through much of the Obama Administration years. Here is a good one:
FAS (Federation of American Scientists) 2012:
"Pivot to the Pacific? The Obama Administration’s “Rebalancing” Toward Asia"
https://fas.org/sgp/crs/natsec/R42448.pdf
"In the fall of 2011, the Obama Administration issued a series of announcements indicating that the United States would be expanding and intensifying its already significant role in the Asia-Pacific, particularly in the southern part of the region. The fundamental goal underpinning the shift is to devote more effort to influencing the development of the Asia-Pacific’s norms and rules, particularly as China emerges as an ever-more influential regional power."
Pivot aka confront China.
Read the section called "Areas of Continuity" where they discuss how Obama's pivot was actually just furthering policies began during the prior Bush Administration. It's a system in action, spanning administrations.
They're doing it in a gradual multi-part rotation. They called it the "pivot to Asia" during the Obama years. That pivot was about dealing with the rising China. Each cycle gets more aggressive and with more resources devoted toward it. With Trump it's called the confrontation with China. They're escalating as they go. The media, as part of the machine, also does its propaganda part as they get their marching orders in part from the military industrial complex: during the Obama years the media called the strategy the pivot to Asia; during the Trump years, they like to use "confrontation" in their news titles; they're providing the cultural atmosphere for what the machine is trying to steer us toward.
The machine, as I'm half-jokingly calling it, is the system of government and power that exists administration to administration and sets continuity policy. It includes structures of power like the Pentagon. That's how the Cold War was operated for example, they didn't entirely flip flop every administration with how the USSR was broadly handled. Most of the government continues from one administration to the next. There are occasionally large, animating ideas that propel the US superpower into action, challenging the USSR was one of those, and China today is another. Nearly the whole of the US system has recognized it can't co-exist with China as previously hoped, most of those pieces that make up the multi-headed power of the US are in agreement to confront China now, spanning from the FBI to the intel community to the US military to the executive branch to almost all of Congress (mostly only varying by degree now).
