New York:  Warning that growing inequalities within and between the nations at a time of widespread economic growth could be dangerous, a top United Nations official has said the process of globalization should be made more inclusive so that it benefits world's poor.

Talking to reporters, Administrator of the United Nations Development Programme (UNDP) Kemal Dervis said economies are expanding at a "virtually unprecedented rate".

But at the same time inequalities are 'exploding' and the poorest are not benefiting from globalization.

"The ever-increasing inequalities lead to tensions, social problems, frustration, alienations with all their dangers," he added.

The Millennium Development Goals (MGDs), which seek to drastically reduce or eliminate several social and economic ill, are a "tremendously powerful mobilizing force" to address these concerns, he said.

While emphasizing that the international community must do its part, he said responsibility ultimately rests at the national level. "It is, of course, the countries at the end of the day that have to achievev the MDGs, he said.

For its part, the UN system would work to improve its development activities, he said. Toward this end, it would carry out the recommendations of a High-Level Panel on UN System-wide Coherence, which made a number of 'vital recommendations' aimed at reducing inefficiency and optimizing resources.
