The United Nations on Monday adopted a stripped-down political declaration on women's rights that seeks to preserve gains under threat but does not advocate new ways to ensure progress toward equality.

The declaration was adopted during the 64th session of the Commission on the Status of Women, which has been drastically reduced from a two-week affair to a single hours-long meeting because of the global coronavirus outbreak.

Twelve thousand participants were originally set to take part.

But Secretary-General Antonio Guterres urged member states not to send delegations to New York, and to cancel debates and other events surrounding the meeting -- the UN's second-largest each year after the General Assembly.

"Centuries of discrimination, deep-rooted patriarchy and misogyny have created a yawning gender power gap in our economies, our political systems and our corporations," said Guterres as the meeting began.

"This simply has to change." he said.

The adopted text follows the main lines of the Beijing Declaration and Platform for Action of 1995, which sought to promote women's emancipation and advancement around the world.

France plans to host a follow-up conference in July to be titled "Beijing+25" aimed at helping protect and ensure the gains women have made over the past quarter-century.

"The situation (of women) is actually not at all where we should be so many years after the Beijing meeting," said Olof Skoog, the European Union ambassador to the UN.

"This is not because there is a lack of focus," Skoog, who is Swedish, told journalists. "It's actually because there is an active political pushback in many countries."

"The ambition this year was to protect what we have rather than to move issues forward," Skoog acknowledged.

The declaration expresses the UN's concern that "overall, progress has not been fast or deep enough, that in some areas progress has been uneven, and that major gaps remain."

One diplomat noted that 75 percent of all members of parliament worldwide are still men.

"In some areas, progress towards gender equality has stalled or even gone into reverse," Guterres said.

"Some countries have rolled back laws that protect women from violence; others are reducing civic space; still others are pursuing economic and immigration policies that indirectly discriminate against women," he said.

The declaration itself noted that 25 years after the Beijing summit, "no country has fully achieved gender equality."

"Significant levels of inequality persist globally, and many women and girls experience multiple and intersecting forms of discrimination, vulnerability and marginalization."

On the question of violence against women -- highlighted by the #MeToo movement against sexual abuse -- the signatories commit to "eliminating, preventing and responding to all forms of violence and harmful practices against all women and girls, in public and private spheres, including in digital contexts."

They also pledge to fight against "human trafficking and modern slavery and other forms of exploitation," and to ensure just treatment and provide support services for "all women victims of violence."

A UN declaration on women is approved every five years.
