PRESIDENT-ELECT Donald Trump's threats to retaliate against US companies planning to shift operations overseas constitute a new risk for multinationals, but may not sway those already planning to offshore jobs.

Mr Trump laid down the gauntlet last Thursday at a campaign-style rally after striking a deal with Carrier to keep about 1,100 jobs in Indiana in exchange for US$7 million in state tax incentives over 10 years.
