The Palestinian-Israeli conflict is not "internal affairs", these are recent remarks made:

Keynote Speech by Xi Jinping at Opening Ceremony of the 10th Ministerial Conference Of the China-Arab States Cooperation Forum, May 30, 2024 https://www.fmprc.gov.cn/eng/zxxx_662805/202405/t20240530_11314383.html

Since last October, the Palestinian-Israeli conflict has escalated drastically, throwing the people into tremendous sufferings. War should not continue indefinitely. Justice should not be absent forever. Commitment to the two-State solution should not be wavered at will. China firmly supports the establishment of an independent State of Palestine that enjoys full sovereignty based on the 1967 borders and with East Jerusalem as its capital. It supports Palestine’s full membership in the U.N., and supports a more broad-based, authoritative and effective international peace conference.

Foreign Ministry Spokesperson Wang Wenbin’s Regular Press Conference on May 22, 2024 https://www.mfa.gov.cn/eng/xwfw_665399/s2510_665401/2511_665403/202405/t20240522_11309866.html

China always firmly supports the just cause of the Palestinian people in restoring their legitimate national rights, supports the two-State solution and is one of the first countries to recognize the State of Palestine. China’s stance on the Palestinian-Israeli conflict is consistent. We believe the immediate priority is to implement UNSC Resolution 2728, realize ceasefire at once, end the unprecedented humanitarian crisis in Gaza and return to the right track of seeking a political settlement of the Palestinian question on the basis of the two-State solution as soon as possible. China will continue to work with the international community to play a constructive role for ending the Palestinian-Israeli conflict as early as possible and promoting a comprehensive, just and lasting settlement of the Palestinian question.
