Prime Minister John Key has brought forward his arrival in Washington today to make an unscheduled meeting with Vice-President Joe Biden at the White House about midnight tonight (NZ time).
Mr Key is in Washington with 40 other invited leaders for President Barack Obama's nuclear security summit. But he is expected to use what opportunities he can, including his meeting with Mr Biden, to promote New Zealand's number one issue with Washington - trade.
Mr Key is expected to politely rubbish the claims US senators made about the effects of the New Zealand dairy industry in the Trans Pacific Partnership trade negotiations which began last month.
