Due to his trading connections in Europe, he was able to exercise great influence on Ottoman foreign policy.[1] Among his achievements were negotiating peace with Poland and influencing the new election of the Polish king. He was awarded the monopoly of the beeswax trade with Poland, and of the wine trade with Moldavia, and maneuvered in the latter country to keep princes favorable to his policies in power. In 1561, Nasi backed Ioan Iacob Heraclid to rule as despot, supported Alexandru Lăpuşneanu's return to the throne in place of Ştefan Tomşa (1564), and ultimately endorsed Ion Vodă cel Cumplit (1572);[6] he was himself considered a suitable choice for hospodar of either Moldavia or Wallachia in 1571, but Selim II rejected the proposal.[6]
