HIGH FINANCE: Europe's leaders are in a high-stakes week of financial diplomacy that could determine Greece's future. The first round began Monday with Germany's foreign minister hosting his Greek counterpart ahead of a meeting in Berlin on Friday between their countries' leaders.

STAY THE COURSE: Germany's foreign minister said Greece must carry out its reform program and said again "a substantial softening of the agreements and the agreed reforms is not possible from the German government's point of view."

WHAT'S THE HOLDUP? Greece has fallen behind on implementing reforms and austerity measures, fueling impatience in Germany and other eurozone countries.
