A doorman prepares the red carpet before the arrival of Saudi Arabian Oil Minister Ali al-Naimi in a Viennese hotel ahead of an OPEC meeting in Vienna, Austria, June 1, 2015. Naimi said on Monday he expects oil demand to pick up in the second half of 2015 while supply decreases, in a sign that the Saudi strategy of defending market share through lower oil prices was working.
