In an op-ed in the The Washington Post on Friday, he said the U.S. was shipping weapons to the YPG, using 5,000 trucks and 2,000 cargo planes to do so according to estimates given by Turkish officials.
The YPG also filed a request for a lobbying office in Washington D.C. in April, using the name the U.S. Mission of the Syrian Democratic Council.
"The political arm of a terrorist group seeking to peddle influence in Washington is a shocking state of affairs, and President [Donald] Trump should block its activity," said the Turkish FM.
"I’m an ally of the Kurdish people. In fact, my party has been honored to receive notable electoral support among Turkish Kurds. I am, however, a sworn enemy of terrorists of all stripes," Cavusoglu wrote, referring to ruling Justice and Development (AK) Party.
He further underscored that the strategy to arm the group had backfired when a U.S. marine was shot by a member of the largest Syrian militia, spearheaded by the YPG and Human Rights Watch also documented the child soldiers were being recruited by this group.
"Arming the YPG directly endangers Turkey and its people, who have already faced decades of fear and violence at the hands of a ruthless and radical terrorist movement", said Cavusoglu. "And now, with the help of our NATO ally, the PKK is being armed to the teeth."
The top diplomat also warned that unless drastic and immediate steps are taken to reverse the course, Turkish citizens will suffer as a result of this "reckless policy".
"Turkey is proud that our actions save not only Turkish but American lives. And it’s because of those lives saved, because of the burden we’ve shouldered in the interest of our collective global security, that Turkey is right to insist that the United States not arm terrorists who are dedicated to our destruction," Cavusoglu wrote.
"It’s time to choose a side.”
