As some European countries take their first provisional steps out of lockdown, member states have come into conflict with the European Commission.
Following a video conference with EU leaders on March 26, Commission President Ursula Von der Leyen said the bloc needed to operate in a coordinated exit from lockdown.
She said failing to do so would "undermine the effectiveness of the tough measures we took".
An internal document sent by the Commission to EU governments said that even phased measures would "unavoidably lead to a corresponding increase in new cases".
It said before restrictions could be lifted the spread of the virus had to be reduced for a significant period and there would have to be enough capacity in intensive care units to cope with a second surge in cases and increased testing, along with mass antibody tests.
Businesses, shops, and schools should open first, followed by the limited reopening of restaurants, bars, and cafes.
However, some countries are anxious to revive their paralysed economies and marginally lift the severe movement restrictions imposed on their citizens.
Last week, Austria, Denmark, and the Czech Republic announced plans to ease lockdown measures.
Now Spain and Italy have followed suit, while Ireland and France have extended their lockdowns until May.
The World Health Organization (WHO) welcomed the slowing rate of infections in some European countries but warned against lifting restrictions too early, saying such a move could prompt "a deadly resurgence."
On Monday, Spain allowed an estimated 300,000 non-essential employees to return to work. These included builders, cleaners, construction, factory, and shipyard workers who are unable to work from home.

The restrictions in place across Spain since March 30 have seen most people confined to their homes.
However, there is now cautious optimism that the pandemic may be reaching its peak with the rate of new infections dropping from 6,278 on April 9 to 3,268 on Monday.
However, some regional leaders have criticised the move amid fears that the lifting of the more extreme restrictions will destroy the public health gains of recent weeks.
Spain's overnight death toll from the virus fell to 517 on Monday from 619 on Sunday, bringing the total death toll to 17,489, the health ministry said.

Besides widespread coronavirus testing, Germany has also significantly raised the bed capacity of intensive care units in hospitals: from 28,000 to nearly 40,000.
Italy, once the epicentre of the virus in Europe, eased some lockdown measures today.

Any lifting of restrictions is unlikely given that Patrick Vallance, the Government's chief scientific adviser, said measures would only be lifted "when we are firmly on the other side" of the peak, with numbers coming down.
Mr Vallance added that "it would be a complete waste of everything everyone has had to do until now" if measures were lifted too soon and the number of deaths rose again.
