The International Herald Tribune editor-at-large, Roger Cohen, is to become a regular columnist on the paper's views and commentary pages.
Cohen, a former foreign editor at The New York Times will keep his Globalist opinion column and will now appear in the IHT on Mondays and Thursdays beginning on 28 May.
Serge Schmemann, editor of the editorial pages, said: "Roger's column has been a great success with the readers.
"The independence enjoyed by writers on the op-ed pages will now enable him to cast his net even wider and to further expand and enrich his stimulating and intelligent journalism."
Executive editor Michael Oreskes said: "Roger has combined tireless reporting and sharp analysis to shed real light on world issues.
"He has richly earned this opportunity to add his own opinions to the wealth of material he offers our readers."
The appointment of Cohen is part of a continuing programme of change at the Paris-based daily since The New York Times Company took full ownership in 2003.
More investment has been made in reporters, news bureaux, print sites and the IHT.com website.
