WASHINGTON (AP) — International Monetary Fund chief Christine Lagarde says the world economy is recovering but fragile and "faces some downside risks."

In an online press conference, Lagarde describes the United States "a strong performer" and China "resilient" despite a recent drop in Chinese stock prices.

She is also optimistic over the 19 countries that use the euro.

"The euro area is beginning to turn the corner ... We have a more upbeat forecast than we have in a long time," she said.

Lagarde called again for Greece's creditors to reduce its debt burden and said the IMF could work with Greece's left-wing government, which has criticized IMF policies.

"There are lots of things that you say (in politics)," she said. "What matters at the end of the day is what you do."
