Fonterra chief executive Theo Spierings said Fonterra intended this year to focus on working with local farmers using New Zealand dairy expertise to develop a fresh milk business.
"We have really laboured the point that we're not trying put Indonesian farmers out of business," Mr Key told reporters last night ahead of a state dinner which was the last engagement of his visit.
"What we are trying to do is of course expand our export opportunities here but the growth in this market like India and Korea and others is so exponential we can't possibly fulfill all of that demand and so working alongside them as partners is important."
