WASHINGTON, Feb. 8 (Xinhua) -- International Monetary Fund chief Christine Lagarde said on Wednesday that greater data transparency could help increase the resiliency of the economy.

"Greater data transparency -- promoted through the IMF data standard initiatives-leads to a 15 percent reduction in the spreads on emerging market sovereign bonds," Lagarde revealed the result of a new IMF policy paper at an event held by the Atlantic Council.

She called on members to improve data transparency, which could help increase economic resiliency.

During the question and answer session, she said that IMF tries to be "ruthless truth tellers" in its assessment of Greece's economic prospects.

In its recent economic assessment for Greece economy, IMF said that Greece's debt was still unsustainable after years of austerity. It called on Greece to continue push forward reforms of its pension, tax and banking systems, which drew opposition from Greek government.
