Chinese health officials on Tuesday said the country plans to speed up COVID-19 vaccinations for elderly people, aiming to overcome a key stumbling block in efforts to ease unpopular “zero-COVID” curbs

Rare street protests in cities across China over the weekend were a vote against President Xi Jinping’s zero-COVID policy and the strongest public defiance of his political career, China analysts said.
Oil prices were also supported by the possibility that major producers could adjust their output plans, with analysts at Eurasia Group suggesting on Monday that weakened demand out of China could prompt a production cut.
The Organization of the Petroleum Exporting Countries and allies including Russia, a group known as OPEC+, hold their next meeting on Dec. 4.
OPEC+ started to lower its output target by 2 million barrels per day (bpd) in November, aiming to shore up oil prices.
Markets are also assessing the impact of a looming Western price cap on Russian oil.
Diplomats from the Group of Seven (G7) nations and the European Union have been discussing a cap between $65 and $70 a barrel, aiming to limit revenue to fund Moscow’s military offensive in Ukraine without disrupting global oil markets.

The price cap is due to come into effect on Dec. 5, when an EU ban on Russian crude also takes effect.
