BRUSSELS, July 20 (Reuters) - German carrier Lufthansa (LHAG.DE) has yet to provide details of fresh antitrust concessions to sooth EU regulatory concerns over its plan to buy Austrian Airlines (AUA), the European Commission said on Monday.

Lufthansa had submitted a new proposal to the Commission, which regulates competition in the 27-country European Union, on Thursday as it races towards a self-imposed July 31 deadline to seal the deal. [ID:nLG458398]

"I can confirm the Commission has had technical discussions with Lufthansa over the weekend, and is still awaiting clarification from Lufthansa concerning its offer of 16 July," Commission spokesman Jonathan Todd told a daily briefing.

He added later that the Commission had no plan to decide this week on whether to clear the proposed takeover.

"There are no current plans for a decision this week," Todd told reporters.

He told the briefing that Competition Commissioner Neelie Kroes had offered to meet Lufthansa Chief Executive Wolfgang Mayrhuber in Brussels on Monday and was still waiting for a reply.

"As of today, midday, he still has not indicated his intention in this regard," Todd said.

Lufthansa shares were up 0.9 percent at 9.37 euros in midday trading, while Austrian Airlines gained 1.2 percent to 4.10 euros.

Lufthansa has taken a tough line with the Commission and the Austrian government, offering new concessions only after Austrian Airlines AUAV.VI approved plans for another savings programme. (Reporting by Foo Yun Chee; Editing by Dale Hudson)
