The United Nations Security Council has adopted five resolutions linked to Syria's three-year civil war.
Russia and China have blocked another three attempts at action by the 15-member body.
The fifth resolution, adopted aims to boost humanitarian access in Syria.
It threatens to take "further steps" in the case of non-compliance, demands cross-border aid access and condemns rights abuses by the Syrian government and opposition armed groups
The UN says 9.3 million people need help in Syria.
The demands sought were for cross-border aid access and an end to shelling and aerial bombardment.
A ban was also sought on barrel bombs.
Western members of the Security Council have been considering a humanitarian resolution for almost a year.
After months of talks, the council adopted a non-binding statement on 2 October urging more access to aid, but that statement produced only a little administrative progress.
UN aid chief Valerie Amos last week urged the Security Council to act to increase humanitarian access in Syria. Mr Amos has repeatedly expressed frustration that violence and red tape have slowed aid deliveries to a trickle.
The United Nations has said that well over 100,000 people have been killed in the civil war.
The opposition Syrian Observatory for Human Rights has said that more than 136,000 have been killed since a revolt against President Bashar al-Assad began in March 2011.
