ExxonMobil has become the latest energy major to invest heavily in new exploration and production projects in the medium term, despite concerns about the current health of the global economy.

Speaking to investors at an annual briefing to the New York Stock Exchange, Rex Tillerson, chairman and chief executive officer of the firm, said that the company would be investing between $25 and $30 billion annually over the next few years in order to meet the anticipated growth in energy demand.

He added that the company will continue to invest in its workers to ensure operational excellence.

"Our commitment to developing advanced technology, our industry-leading operational and project-management capabilities and exceptional employees continue to position the company as the partner of choice for resource owners around the world," he said.

ExxonMobil has also this week announced that it will partner with the National Community Action Foundation to train tens of thousands of workers in the weatherisation sector.
