Business will be on the G20 agenda. Investors will watch talks between the United States and China about all signs of a breakthrough that would ease tensions and help avoid higher tariffs.
President Donald Trump and his Chinese counterpart, Xi Jinping, have dinner on Saturday.
"I think we are very close to China, but I do not know that I want to do that because what we have right now is billions and billions of dollars to the United States in the form of tariffs or taxes," Trump told reporters on Thursday.
2. Oil prices in focus: The US oil price has fallen by about 22% last November. Annual futures declined by another 1 percent on Friday, below $ 51, when concerns about oversupply remain.
Russian President Vladimir Putin and Saudi Arabian Crown Prince Mohammed bin Salman, leaders of the world's two largest oil producers, will meet this weekend in the G20.
Both countries are the main signatories of the agreement to reduce supply and raise prices. Speaking that OPEC and Russia may agree further cuts at a meeting next week in Vienna.
That's exactly what Trump does not want. Last week, he posted the tweeted "Thank you to Saudi Arabia" for keeping prices down, "but let's go down," he added.
Deutsche Bank shares fell by another 2%, bringing total losses to 48% by 2018.
Prosecutors claim that the largest German creditor is suspected of helping clients set up coastal companies in tax havens. Investigators also address the question of whether Deutsche Bank did not record suspicious transactions.
Investigation is among the other questions about the business strategy and direction of the bank.
5. Economy: The Federal Reserve, on Thursday, paved the way for rising interest rates in December, but sent a clear signal to investors that it would be more flexible with its plans to raise rates in 2019.
The record of the US Central Bank's November policy meeting showed that "almost all participants" agreed that the next rate increase would probably be "fairly soon" if the incoming data were consistent with the current expectations of policymakers.
