"The United States has become a market for Indonesias fishery products. If President Donald Trump implements the protectionist program, it will affect Indonesian businesses in the maritime and fishery sectors in the long term," Halim said.
He added that the protectionist program included the increases in tariff on imported goods and the improvement of quality control of fishery products.
"It also increases the competition for fishery products from other countries," he stated.
Indonesia is the second biggest exporter of fisheries products to the US, according to data from the Center of Reform on Economics (CORE) Indonesia.
Therefore, he urged the government to strengthen Small Medium Enterprises (SMEs), in particular fishery products through the provision of subsidies and market access.
In addition, the government should also facilitate capacity building and protect SMEs from the marketing of similar fishery products from other countries, he noted .
