South Korea pledged US$350 billion in United States investment, including $150 billion for shipbuilding cooperation, under a joint fact sheet adopted after the summit between President Lee Jae Myung and Donald Trump.[^1]

The Jones Act is Section 27 of the Merchant Marine Act of 1920, codified at 46 U.S.C. Sec. 55102.[^2] It requires ships carrying cargo between two U.S. ports to be built in the United States and manned and primarily owned by U.S. citizens.[^6] Building major ships in the U.S. costs five times more than in South Korea or Japan.[^5]

The law has been waived and suspended before. President Bush temporarily waived the Jones Act in 2005 for Hurricane Katrina relief; President Obama refused to suspend it in 2010 for Deepwater Horizon cleanup; it was suspended in 2012 after Hurricane Sandy for oil tankers on the East Coast.[^4]

The Merchant Marine Act of 1936 established the United States Maritime Commission and required a U.S. merchant marine with U.S.-built ships and citizen crews.[^3] The United States has lost competitiveness in shipping and shipbuilding, especially for large oceangoing ships needed by noncontiguous jurisdictions.[^7]
