There isn't much time left for Greece: Merkel

Merkel also insisted that solidarity with European partners and the IMF would be contingent on Greece's initiative to implement reforms

German Chancellor Angela Merkel on Monday warned that time is running out for a deal with Greece's creditors, and insisted that solidarity with European partners and the International Monetary Fund would be contingent on Greece's initiative to implement reforms.

"There isn't much time left. Everyone is working intensively. The day after tomorrow there will be opportunity to discuss it with the Greek prime minister. Every day counts now," Merkel said in a press conference after the conclusion of the G7 summit in the Schloss Elmau hotel in southern Germany.

Merkel added that the Greek financial crisis was one of many issues discussed in the meeting, which she attended on Monday along with Jean-Claude Juncker, the president of the European Commission, or EC, and managing director of the IMF, Christine Lagarde.

Merkel reiterated that all summit attendees want Greece to remain in the Eurozone, but reminded that there are rules that govern the union and that European and international solidarity must be matched by member countries' own efforts.

Merkel argued that measures taken by the troika (EC, IMF and the European Central Bank, or ECB) proved to be effective in the cases of Ireland, which thrived after applying a tough reform program, Spain and Portugal, which created jobs despite ongoing high unemployment rates.

Merkel pointed out that the situation in Cypress also leads to a path of "success".

The German chancellor confirmed her intention to meet again with Greek Prime Minister Alexis Tsipras in Brussels on June 17 under the auspices of the EU summit meeting with the Community of Latin American and Caribbean States, or CELAC.

In her view, the proposal presented to Athens by the three creditor institutions is "a breakthrough" that must be negotiated.
