The US tariff deal with Indonesia is set to ease critical mineral export restrictions from the Southeast Asian country to the US, the White House said Tuesday.

The Trump administration expects that Indonesia’s decision to bring down trade barriers will result in at least $50 billion in additional market access for US goods.

Indonesian sovereign wealth fund Danantara plans to sign an $8 billion engineering, procurement and construction contract with U.S. engineering firm KBR Inc to build 17 modular refineries, according to two sources familiar with the matter and an official economic ministry presentation seen by Reuters.

The new US tariffs could hurt the Philippine economy more than Indonesia’s, even though both face a 19-percent import tax, as Manila’s earlier edge may have been erased by President Donald Trump’s higher-than-expected tariff announcement.
