According to Haoliang Xu, the Assistant Secretary-General of the United Nations and Director of the Bureau for Policy and Programme Support at the United Nations Development Programme, the progress towards achieving the Sustainable Development Goals (SDGs) has been uneven. Here are some key points to consider:

• Some progress has been made towards achieving the SDGs, including improvements in access to health care and education and a decrease in extreme poverty.
• However, there are still major challenges to achieving the SDGs, particularly in relation to environmental sustainability and reducing inequality.
• The COVID-19 pandemic has created new obstacles to achieving the SDGs, particularly in areas like access to health care and education.
• Strong partnerships and international cooperation are essential to achieving the SDGs, particularly in relation to financing development and tackling climate change.
• New technologies and innovations can also play a key role in achieving the SDGs, from renewable energy to digital connectivity.

Overall, while progress has been made towards achieving the SDGs, there is still a long way to go, and global cooperation and action are needed to make sure no one is left behind.
