Austria and Qatar have boosted their bilateral relations with agreements on double taxation and air transport. While one accord ensures that income and capital aren't taxed twice, the other provides the basis for future negotiations on, among other things, the number of flights between the two countries, AP reported. The signing ceremony Thursday took place in the presence of Qatar's Emir, Sheikh Hamad bin Khalifa Al-Thani, who is currently on an official visit to the Alpine republic and a high-ranking economic delegation.
