Given this paragraph about the First Treaty that was signed after the Russo-Japanese War, was there a secret component?

Context:
After the Russo-Japanese War, the First Treaty was signed on 30 July 1907 by Motono Ichirō, the Japanese Ambassador in Moscow, and Alexander Izvolsky, the Foreign Minister of Russian. The treaty was divided into two parts: one is open agreement, which respected the treaties concluded between the two countries and China, respected China's independence, promoted open doors, and achieved equal opportunities and another is secret agreement, which defined the scope of Japan's interests in Southern Manchuria and Russia's interests in Northern Manchuria and Japan recognized Russia's interests in Outer Mongolia, and Russia recognized Japan's interests in the Korean Peninsula.<|im_end|>
