UPDATE 1-Daimler says China agreed to adjust pace of electric car quotas

* Daimler says China agreed compromise on electric car quota

* Daimler CEO says pace of introducing quotas adjusted

* Daimler CEO says compromise discussed at Germany summit (Adds comment from Daimler chief executive)

BERLIN/RASTATT, June 2 (Reuters) - China has agreed to adjust the pace of introducing stringent domestic quotas for electric car sales, Daimler Chief Executive Dieter Zetsche said on Friday after an auto industry lobbying effort ahead of a Germany-China summit held this week.

In a policy draft in September, Chinese policymakers proposed that 8 percent of automakers' sales be battery-electric or plug-in hybrid vehicles by 2018, sparking protests from domestic and international carmakers.

After a meeting with German Chancellor Angela Merkel in Berlin on Thursday, Chinese Premier Li Keqiang said a "solution" for implementing the quotas had been found, though he gave no details.

Asked what had been agreed between Germany and China, Daimler Chief Executive Dieter Zetsche told Reuters: "What we talked about was the timeline, the pace of this transition. I think we reached a result which is satisfactory for everybody."

Zetsche said that he could not give further details given that the Chinese and German participants in the negotiation had also not divulged details of the compromise.

Maintaining and extending its current strong position in China is crucial for Germany's auto industry, led by Volkswagen , Daimler and BMW, and its broader economy.

Handelsblatt, citing industry sources, said China had agreed to delay the introduction of the rule by a year and allow firms to make up for inadequate electric sales volumes later. Measures were also being investigated to allow German firms to limit their transfer of technology to China, Handelsblatt said.
