South Korea’s top policy chief said the country made “substantial progress” on most key issues in tariff talks with the US, following a weekend of meetings that also saw Seoul’s top tycoons attend a golf event with Donald Trump at his Mar-a-Lago estate.

The two countries reached broad agreement on many issues, though several points still require further negotiation, Kim Yong-beom, the presidential policy chief, said in a televised briefing Sunday. He added the chances of finalizing a deal at the upcoming Asia-Pacific Economic Cooperation summit had increased.
