South Korea’s government has announced that it has finalised an agreement to build nuclear-powered submarines in partnership with the United States.The agreement marks a significant step in South Korea’s relations with the US and comes amid a period of growing tensions on the Korean Peninsula: with the nuclear-armed North Korea, and an expansionist China to the west. The agreement between the US and South Korea comes as leaders from both countries reached a broad trade deal earlier last month that would see reciprocal tariffs cut to 15% from 25%. US President Donald Trump had slapped a tariff rate on Seoul of 25% earlier this year – which his counterpart Lee Jae Myung managed to negotiate down to 15%, after Seoul said it would invest $350bn (£265bn) in the US, including $200bn in cash investment and $150bn in shipbuilding. Who decides the countries to have nuclear wepoans ?
