According to METI news release on April 14, it was officially announced that Japan will start EPA negotiation with Peru. The detailed schedule outline will be discussed later.
As for import from Peru to Japan, the main items are zinc ore, copper, and fish meal.
From export from Japan to Peru, its 60% of amount are vehicle related products.
Currently Peru impose 9% of customs duty to passenger vehicle and bike.
As Peru have already started EPA with Korea (under negotiation) and China (signed), Japanese industries have concern about substantial inequality in customs duty compared with rival countries.
