Biggest Trading Partners - Turkey

Turkey is not Arab, except for a tiny minority. It's true though that also other Muslim countries boycott Israel, but there are some exceptions, like Egypt and Jordan to some extent, while they had excellent relations with Turkey until recently, Israeli air force often having practice over Turkey as there isn't enough (suitable) space in Israel.

Turkey is one of Israel's oldest (and only) allies, or the closest thing they have to that, in the region. The Arab League boycott of Israel goes back to the Arab invasion of Israel in May 1948, the day after the country declared independence. Turkey was not a party to that invasion. They became the first Muslim-majority country to recognize Israeli independence in March of 1949. The Turkish Republic was founded as a secular republic in 1923, after the collapse of the largely secular Ottoman Empire, led by Mustafa Atatürk who introduced many far-reaching liberal reforms. The Turkey of '48-'49 was still very much Ataturk's Turkey; though he had died 10 years prior his political party was still in control.

That doesn't mean relations have always been easy. Turkey is in a weird place, always trying to balance between East and West, Europe and Asia, the Christian and Muslim worlds, tradition and modernity...

... and between Ataturk's vision of a secular republic and the country's conservatives' desire for politics with a more theocratic bent. Lately the country has been dominated by Erdogan, an Islamist, and relations between Turkey and Israel have soured, particularly following the last so-called Gaza War, as pan-Islamic ideas have gained traction there and opposition to Zionism and to Israel has always been about pan-Islamism and pan-Arabism.

but Turkey is not Arab as pointed out. They have historical disagreements with virtually all of their neighbors and no true friends. Their regional politics have always been about this complex balancing act I described while playing adjacent countries off of one another. So that includes, for example, joint military exercises with Israel as a bulwark against Hizbollah (shia)-dominated Lebanon, Alawite (basically shia)-controlled Syria, and explicitly theocratic (and shia) Iran. Turkey is sunni.

but then they will also play these countries against the Kurds (whose state of Kurdistan, if ever recognized, would claim more territory from Turkey than anywhere else), and of course Da'esh whom everyone hates.

Turkey's biggest export to all of its neighbors is hatred of Turkey.

Don't forget that they also have taken on a vast majority of Syrian refugees - 3 million by last count.
