In return for lower tariffs, it has had to make concessions so as to balance its trade with the Americans. Among other things, Indonesia has accepted US demands to ease curbs on American auto imports. The US also ventured into non-trade issues during the trade talks. However, Indonesia has told the US that it cannot meet this South China Sea demand, nor the demand to purchase US-made drones, said the two sources. Jakarta is adamant that these requests are not related to the aim of the tariff talks, which is to balance trade between the two countries, they added.
