* Tokyo to Mexico flights to begin Feb. 15
* ANA sees boost to business travel from deepening economic ties
* White House has floated idea of 20 pct tax on Mexican goods (Adds CFO comment, flight details, context)
TOKYO, Jan 27 (Reuters) - Japan's ANA Holdings Inc on Friday stuck with a plan to begin daily flights to Mexico next month, but expressed concern that U.S. tariffs on Mexican exports as suggested by President Donald Trump could dampen demand from business travellers.
"We will need to keep watch on what impact the new administration will have on the flow of people and goods," Yuji Hirako, the chief financial officer of Japan's biggest airline, said at a briefing after ANA released third-quarter earnings.
"If there is a serious policy shift to protectionism that will hurt the global economy, including us," he said.
Since Mexico, the United States and Canada implemented the North American Free Trade Agreement (NAFTA) 23 years ago, Japanese automotive manufacturers, including Toyota Motor Corp and Nissan Motor Co Ltd, along with their U.S. and European rivals, have expanded production in Mexico, shipping much of the output to the U.S. market.
The White House on Thursday floated the idea of a 20 percent tax on goods from Mexico to pay for a wall along the southern U.S. border to prevent illegal crossings, after Mexican President Enrique Pena Nieto scrapped a planned trip to meet with Trump.
Tariffs could force carmakers to shift production to other sites and in doing so cut demand for business travel to Mexico.
ANA, which announced the start of direct flights to Mexico in May, has been considering starting the service since at least 2014, when business executives accompanied Japanese Prime Minister Shinzo Abe to Mexico to deepen economic ties.
