Mrs Merkel sent shockwaves through Washington and London by saying on Sunday that Europe must take its fate into its own hands, implying that the United States under President Donald Trump and Britain after its Brexit vote were no longer reliable partners.
"Anyone who speeds up climate change by weakening environmental protection, who sells more weapons in conflict areas and who does not want to politically resolve religious conflicts is putting Europe's peace at risk", Gabriel said.
The German politician added that the West had become smaller and weaker due to the United States' policies.
The sharp words from Foreign Minister Sigmar Gabriel came after Trump concluded his first official tour overseas which took him to Saudi Arabia, Israel, Brussels and then Italy for a G7 summit. "The Trump administration wants to terminate climate agreements, wants to enforce military action in crisis regions, and won't allow people from certain religious circles to enter the USA", he said. "Those who do not oppose this U.S. policy are guilty".
"But we have to know that we must fight for our future, on our own, for our destiny as Europeans - and that's what I want to do together with you", she added. Merkel is expected to win a fourth term as Chancellor when Germany heads to the polls in September.
Further talking about the upcoming G20 summit in Hamburg in July, Modi offered India's full support for a successful outcome.
On Indo-German ties, he said India sees Germany as an important partner in the national flagship programmes of Make in India, Skill India, Start-up India, Clean India and Smart Cities.
Trump reportedly tells 'confidants' US will leave Paris climate deal
Mr Trump's attitude to climate change made the G7 talks " very difficult" said German Chancellor Angela Merkel (left). Among other things, the group committed to take the lead on the implementation of the Paris Climate Accord.
A like-minded pro-European and multilateralist, Macron gives Merkel a reliable partner with whom she can move forward in Europe on issues like defense and security cooperation, migration and euro zone reform.
But Seibert also took the opportunity to stress that Merkel remained "a deeply convinced trans-Atlanticist".
He attended a private dinner hosted by German Chancellor Angela Merkel at Schloss Meseberg, some 65 km from Berlin, which is the country retreat of the German Chancellor and the official state guest house of the government.
"Both (the German and Indian) governments are firmly committed to strengthening economic relations", Mr Modi said in an interview with Handelsblatt newspaper. In a tweet published Sunday, Trump hailed his trip to Europe as "a great success for America". His failure to voice clear support for NATO's mutual defense doctrine, Article 5, and to evoke Russian Federation as NATO's prime threat also irked Berlin and other allies.
He also censured 23 North Atlantic Treaty Organisation members for not spending 2 percent of their GDP on defense.
Their their final summit communique, the leaders of the G7 countries said that the United States has not yet joined the consensus on the issue of climate change, which was reached within the framework of the Paris accord of 2015, as the country was reviewing its policies on the matter. "She has been relatively consistent on this".
"It's not a choice against the U.S., she's still engaging as a powerful European leader and she is someone whose voice who will be heard around the table".
A ceremonial welcome will be held for Modi at the Chancellery, the office of the German Chancellor, following which he will hold formal talks with Merkel as part of the India-Germany Intergovernmental Consultations [IGC]. She also spoke of Britain's decision to leave the European Union, which means the bloc will lose its second-largest economy and one of its two nuclear powers.
