The TPP wasn't perfect, but tearing it up has serious downsides. For one, it potentially hands China, which was excluded from the TPP, a golden opportunity to expand its influence with America's former trading partners, who will now have to renegotiate the terms and conditions of their trade with the U.S. individually rather than collectively and thus from a relatively weaker position. They might easily conclude they can get a better deal from their giant neighbor China than from what they view as an increasingly unreliable U.S. The American withdrawal also creates a huge economic power vacuum that other countries, including China, will rush to fill, giving them the chance to eventually supplant America's leadership role in the region. In unilaterally scrapping the TPP, the Trump administration may inadvertently have handed China a public relations and propaganda victory it could never have won on its own.
