NEW YORK – President-elect Donald Trump has said he will hold a press conference on January 11, during which he has previously indicated he would unveil plans to avoid any conflict of interest between the White House and his business dealings.

Trump has not held a press conference since July, and his announcement on Tuesday gave just the latest date set for the much-delayed event previously due to take place on December 15. He was elected in November.

In a tweet, Trump said: "I will be having a general news conference on JANUARY ELEVENTH in N.Y.C. Thank you."

Precedent has seen American presidents-elect field numerous press conferences during the transition to power to discuss matters such as their choices to fill their cabinet and policy plans for the incoming administration.

Instead Trump has relied largely on rallies, photo ops, select interviews and - in unprecedented fashion - on tweets.

He has largely snubbed thus far the tradition that the presidential news conference has become.

His methods of communicating news about the transition have been unorthodox for an incoming head of state.

Last month, he unexpectedly announced to reporters camped in the lobby of his Manhattan Trump Tower skyscraper that Masayoshi Son - the flamboyant head of Japanese telecoms giant SoftBank and a self-made billionaire – had announced a US$50 billion investment in the US that would create 50,000 jobs.

Economic announcements of this magnitude are rare and generally take place through a news release or a carefully planned press conference, requiring the efforts of many public relations experts who carefully consider every word and gesture.

Steven Mnuchin, tapped to become Secretary of Treasury, and Wilbur Ross, the commerce pick, announced on CNBC television that they had been appointed to their Cabinet positions by Trump.

The official announcement was published several hours later.

As for the nomination of his future Secretary of Defence, James Mattis, the president-elect announced the pick during a rally in Cincinnati, Ohio, the first stop of his "thank you tour" in the industrial states that gave him the presidency. – AFP
