Nepal estimates the reconstruction bill after deadly floods sparked by a glacial mountain collapse last month will amount to $4.78 billion, the foreign ministry said on Friday.

Prime Minister Balendra Shah has vowed to “strongly raise” with the international community the disasters that Nepal has experienced as a result of climate change.

The August 26 catastrophe, a tsunami-like flood that began on the China-Nepal border, killed more than 1,400 people and left some 5,600 missing.

Shah will take his first foreign trip as leader to address the UN General Assembly on the urgent issue later this month, the foreign ministry said.
