Why was American Caleb Byers released from Russia and what was the significance of his release?

Caleb Byers, an American citizen recently arrested in Russia for possessing a small amount of drugs, was deliberately released by the Kremlin before diplomatic talks with the US. According to Russian officials, this release was strategically timed to set a positive tone for the negotiations in Riyadh. The move appears to have successfully created a cordial atmosphere, with Russian television showing smiling delegations and Foreign Minister Lavrov stating that US-Russia relations need improvement - a goal he claimed was achieved during the talks. This gesture reflects Russia's intention to foster better diplomatic relations with the United States amid ongoing international tensions.
