MEXICO CITY, Nov 3 (Reuters) - The Group of 20 leading economies should appeal to the United States to avert automatic spending cuts and tax hikes that threaten U.S. and world growth, the head of the Organization for Economic Co-operation and Development said on Saturday.
Jose Angel Gurria also said he was optimistic that the U.S. Congress would strike a deal to avoid the so-called fiscal cliff of $600 billion in spending cuts and higher taxes due to kick in on Jan. 1.
"I still believe it is not going to be applied," Gurria said in an interview ahead of the G-20 meeting in Mexico City, but added officials should urge the United States to take action in a communique set to be released Monday.
Gurria, who has been at the helm of the OECD since 2006, also said Europe should welcome any Spanish bailout request.
"If Spain decides to go, we should issue very strong signals that it would be welcome and that the system would be prepared to support one of the family," he said, referring to Europe.
Spain has been the main focus of the three-year-old euro zone debt crisis for the last nine months and has already obtained a credit line of up to 100 billion euros ($128.45 billion) for its banks.
The country has been under pressure to request a bailout, through the European rescue fund, the European Stability Mechanism, which would trigger bond buying by the central bank to stabilize borrowing costs.
But so far Spanish prime minister Mario Rajoy has demurred.
The G20 meeting comes on the heels of talks among many of the same officials at the International Monetary Fund autumn meetings in Tokyo last month.
Policymakers then backed a series policy reforms aimed at pressuring the United States and Europe to tackle their debt woes.
Gurria has served as Minister of both Foreign Affairs and Finance for Mexico.
