Dairy exports to China by New Zealand competitor the United States were down 47 per cent in October due to retaliatory trade tariffs.
But US dairy exports to other countries were up 14 per cent in October, the latest month for which figures are available, with large gains in sales to southeast Asia and Mexico, said the US Dairy Export Council.
US sales to China of wholemilk powder, New Zealand's main dairy export, were down 97 per cent between July and October, compared with the same period in 2017, the council said.
China imposed additional tariffs on US imports from July. The dip in wholemilk powder sales to China equalled 1288 tons per month over the four months.
However, total US wholemilk powder exports had doubled this year, said the council.
