The Prime Minister set out on his 10-day tour of Latin America with not much new business in prospect. He was accompanied by representatives of firms such as Fonterra, Zespri and Mighty River Power whose industries underline the similarities of our economies. Those similarities might always limit the trade we can do with the nearest continent to our east, but trade is not the prime consideration in this relationship.
From our position in the world we ought to have more to do with South America. Chile and Argentina are closer than they look on a flat map. Our proximity on a direct route over Antarctica has encouraged the airlines of both countries to operate services to New Zealand. Argentina's has fallen victim to that country's economic mismanagement in recent times, but Lan Chile still flies here.
Travel ought to have made us as familiar with Santiago as we are with Singapore or Los Angeles. This country's cultural and educational exchanges with the Spanish-speaking nations on the Pacific rim could be as rich and well established as they are with Asia. Hispanic migration could be a larger part of our population mix.
John Key visited four countries: Chile, Mexico, Colombia and Brazil. Chile is a fellow founder of the trade pact that aims to become the Trans-Pacific Partnership, Mexico is also in those negotiations. Colombia is beginning to realise its potential after pacifying a long insurgency and Brazil is being ranked with Russia, India and China as one of the world's future economic giants.
Brazil has also shown that popularly elected left-wing governments can be sensible and reliable economic managers. Its recent progress is a welcome contrast to Venezuela, where an oil price boom has been largely squandered by the populist Hugo Chavez, who died last week.
