三国協商
When Austria-Hungary found itself at war in August 1914 with the rival Triple Entente, Italy proclaimed its neutrality, considering Austria-Hungary the aggressor. Italy also defaulted on the obligation to consult and agree to compensations before changing the status quo in the Balkans, as agreed in 1912 renewal of the Triple Alliance. Following parallel negotiation with both Triple Alliance (which aimed to keep Italy neutral) and the Triple Entente (which aimed to make Italy enter the conflict), Italy sided with the Triple Entente and declared war on Austria-Hungary.
