Turkey wanted the final G20 communique of the world's financial leaders meeting in China to include an endorsement of the current government after the failed coup attempt, but did not succeed.
Turkey's Deputy Prime Minister Mehmet Simsek, attending the meeting, denied Ankara had sought such a reference, tweeting: "We have no such initiative."
But European Commissioner for Economic Affairs confirmed on Sunday that Turkey had sought such a mention.
"It is true that Turkey wanted a line on that, that was debated in the drafting sessions but the minister, after talking to a few of us, estimated that it was wiser not to raise this issue in the G20 session itself. That was wise," Moscovici told a news conference.
Finance ministers and central bank governors from 20 of the world's biggest economies (G20) met in the Chinese city of Chengdu to discuss, among others, risks to the global economic outlook, clouded by Britain's decision to leave the European Union.
The Turkish government, which introduced a state of emergency on Wednesday after the failed coup and is considering bringing back the death penalty for the plotters, wanted the final communique of the G20, closely watched by markets, to include a paragraph on Turkey.
"Strengthening the rule of law is fundamental for sustainable development and we support the legitimate government of Turkey in its endeavours to enhance economic stability and prosperity," the additional paragraph of the G20 was to say.
Officials from European Union countries, however, did not support that and the final communique did not mention Turkey.
Western countries backed Turkey's government during last week's failed putsch, but are increasingly worried about Ankara's subsequent crackdown against thousands of members of the security forces, judiciary, civil service and academia.
