  • Trump's shift to a transactional, bilateral approach to trade from the current rules-based, multilateral model is "a step back," said Steve Okun, vice chairman of the Asia Pacific Council of the American Chambers of Commerce.
  • Businesses with global supply chains won't be able to take advantage of bilateral trade deals, Okun said.
  • Okun said he wouldn't be surprised if the renegotiation of rules of origin in Nafta began with the terms negotiated in TPP.

U.S. President Donald Trump's move to chuck the trade rulebook for a maverick style has been "a step back" for global commerce, said Steve Okun, vice chairman for the Asia Pacific Council of American Chambers of Commerce.

"[For] the four presidents preceding Donald Trump, we had a focus on a multi-lateral system that was rules based, and that evolved over time and it went from FTAs (free-trade agreements) and WTO (World Trade Organization) and up to the TPP (Trans-Pacific Partnership)," Okun told CNBC's "Street Signs" on Friday.
