Ms Sturgeon outlined her support for the Scottish government’s response and called for dialogue rather than criticism.
The leader of the Scottish National Party (SNP), Ms Sturgeon tweeted the Scottish Government’s response to the result after the Catalan parliament voted for independence today.
She posted: “We respect position, the people of Catalonia must have ability to determine own future”.
The response from the Scottish Government also said: “While Spain has the right to oppose independence, the people of Catalonia must have the ability to determine their own future.
“Today’s Declaration of Independence came about only after repeated calls for dialogue were refused.
“Now, more than ever, the priority of all those who consider themselves friends and allies of Spain should be to encourage a process of dialogue to find a way forward that respects democracy and the rule of law.”
The Scottish government called on the European Union to resolve the situation peacefully and democratically.
Her comments came after the UK Government said that it will not recognise the declaration of independence.
Prime Minister Theresa May’s official spokesman said the declaration was based on a vote which had been declared illegal and that the UK wanted to see the unity of Spain preserved.
Scottish separatists believe the two causes are linked.
The First Minister has been accused of mixed messaged on Catalonia as she supports both self-determination and the European Union, which has said will not recognise the region.
Twitter user Richard Kakaso responded to Ms Sturgeon: “Majority of Catalans want to stay part of Spain. Majority of Scots want to stay part of UK. Just a quick reminder on both of those facts.”
Earlier this month, Ms Sturgeon said that the people of Catalonia “were not left with any choice” but to hold and independence referendum in defiance of the Spanish government.
The First Minister also claimed that the EU has failed Catalans by not condemning the “grotesque and unacceptable” violence of Spanish police.
It is thought that although she may support an independent Catalonia, she knows that accepting the result could distance those countries she needs on side during the Brexit process.
Speaking on the BBC’s Andrew Marr show, Ms Sturgeon said: “What I think has to be recognised is the strength of feeling in Catalonia.
“I think it’s now time for dialogue to replace confrontation. You cannot simply say the right of a people to choose their future is illegal in all circumstances.”
