The ongoing saga of the attempt to restart talks to revive Iran’s 2015 nuclear deal with world powers in … still ongoing. 
A couple of weekend updates.
The Financial Times reported the EU’s foreign policy chief Josep Borrell told the news outlet that he was seeking a “middle way” to end the impasse

Aljazeera have an ungated report separately:

EU coordinator Enrique Mora to visit Tehran on Tuesday (he is the EU coordinator for talks on restoring Iran’s 2015 nuclear deal with world powers)
Iran making positive statements on the planned visit: “Considering the EU’s role in exchanging viewpoints between Tehran and Washington, Enrique Mora’s trip to Tehran can be regarded as a new step for constructive negotiations surrounding the few but important remaining issues,”. But added, less positively: „Iran has remained in the negotiations despite “the persistence of hostile approaches by the US against our country” that it said goes against the spirit of constructive negotiations.“

Pretty much every weekend we get some form of update on these negotiations. Talks to revive the nuke deal between Iran and the world have been on hold since March, though. Do not hold your breath. 

Shanghai officials today said the covid outbreak was under ‚effective control‘ on Friday and that cases have been on a ‚continuous downward trend‘ since April 22.
The city has been under lockdown since April 1 and there’s no visibility to when that will end. About 2.3m people are in sealed-off areas while 16.7m are in lower-risk ‚prevention zones‘ but how those rules are applied are a point of frustration for residents.
The latest number of cases was 4024 yesterday but the vast majority of those were in quarantine centers. There were 245 locally transmitted cases reported on Saturday.
A survey of Japanese manufacturers on Thursday showed how difficult it is to re-open factories under ‚closed loop‘ rules. According to the SCMP:

The
Shanghai Japanese Commerce & Industry Club said on Thursday of 54
firms that responded to a survey it conducted between April 27-30, 63
per cent responded that their factories had yet to resume operations.

Out
of the 37 per cent that have resumed operations, over three-quarters
said production was at or below 30 per cent of normal levels.
That’s a bit dated now but underscores how difficult it will be to reestablish supply chains.
Meanwhile, the centre of the outbreak appears to be moving to Beijing where the Chaoyang district ordered another round of mass testing along with a stop to construction work and office closures. On Saturday, 78 cases were reported compared to 68 a day earlier.
Here’s a great chart from Exante showing what looks like a de facto lockdown in Beijing:
