In addition, such crimes will be subject to stiffer penalties, according to a bill expected to be presented by the government on Thursday.
The proposal includes a wider definition of both crimes, which are currently difficult to prosecute.
The minimum sentence for spying on refugees will be increased from simple fines to prison time.
The definition of spying on refugees will also be expanded to “unauthorized intelligence activity against a person”, according to the proposal, and is meant to address cases in which foreign powers attempt to spy on regime critics who have fled in Sweden.
Current legislation stipulates that the spying must take place in secret, but now the government also wants to cover cases in which information gathering takes place openly and is often followed by threats.
“This is unsavoury activity that we must take very seriously. Many feel that authorities in their previous home countries are trying to put pressure on them and keeping tabs on what they do. Considering that many refugees have relatives back in their home countries, things can go quite badly,” Justice Minister Beatrice Ask told the TT news agency.
Iran, China, Syria, Uzbekistan, and Eritrea are among the countries that are sometimes accused of spying on refugees in Sweden, but very few cases ever make it to court.
The proposed law will also broaden the definition of unauthorized intelligence activity directed against Sweden.
“We’re widening what can be criminalized and it’s directed toward activities that one can compare with the first stage of spying,” said Ask.
The new definition targets the secret gathering of information and scraps a current requirement that the purpose of the information gathering must also be proven.
“This has been sought after for a long time by the Swedish Security Service (Säpo) and others who investigate these types of crimes. They think it’s been too hard to bring forth evidence against the perpetrators,” said Ask.
Penalties for spying against Sweden will also tougher according to the new bill, to between six months and two years in prison, or four years of the crime is considered aggravated.
Stronger sentences makes it easier for investigators to have suspects held on remand or get authorization for telephone wiretapping and other “secret coercive measures”.
