• Mexico withdraws Harvey aid offer as it focuses on earthquake recovery

The United Nations has imposed a fresh round of sanctions on North Korea after its sixth and largest nuclear test.

The measures restrict oil imports and ban textile exports – an attempt to starve the North of fuel and income for its weapons programmes.

The US had originally proposed harsher sanctions including a total ban on oil imports.

The vote was only passed unanimously after Pyongyang allies Russia and China agreed to the reduced measures.

The sanctions, which were passed at a UN Security Council meeting on Monday, were met with anger by North Korea.

A statement on state news agency KNCA warned that if the US did eventually push through harsher sanctions, North Korea would “absolutely make sure that the US pays due price”.

The US call last week for a total ban on oil imports was seen as by some analysts as potentially destabilising for the regime.

The new sanctions include:

• Limits on imports of crude oil and oil products. China, Pyongyang’s main economic ally, supplies most of North Korea’s crude oil.
• A ban on exports of textiles, which is Pyongyang’s second-biggest export worth more than $700m (£530m) a year.
• Measures to limit North Koreans from working overseas, which the US estimates would cut off $500m of tax revenue per year.

A proposed asset freeze and a travel ban on North Korean leader Kim Jong-un were dropped. A total ban on oversees workers was also reduced.

In the meantime, Mexico has withdrawn its offer to help victims of Hurricane Harvey in Texas, saying it needed to redirect resources to its own southern states which are still reeling from last week’s massive earthquake.

As torrential rains lashed Houston in late August, Mexico offered to send food, generators, medical staff and mobile kitchens to help hurricane victims, but on Monday, the foreign ministry said that the aid was needed at home after Friday’s quake.

In a statement, the ministry said that the death toll from magnitude 8.1 earthquake had reached 96, while officials estimate 2.5 million Mexicans are in need of some sort of assistance.

Aid has arrived in some of the affected areas – especially the municipality of Juchitán on the Isthmus of Tehuantepec – but local media reported that survivors in some marginalized areas were still waiting for relief to arrive.

“Given these circumstance, the Mexican government will channel all available logistical support to serve the families and communities affected in the national territory,” the foreign ministry statement said.

The temblor reduced buildings to rubble in swaths of the poor states of Oaxaca and Chiapas, where residents pick through crumbled concrete in search of survivors.

Oaxaca governor Alejandro Murat told local media that some 12,000 homes had been damaged. Residents in some cities were sleeping in the streets, scared to enter their homes as more than 1,000 aftershocks have rattled the region.

One widely-shared image of the destruction showed a man rescuing a Mexican flag from the rubble of the partially destroyed city hall in Juchitán.

“The flag is our national symbol. It is part of our identity and I was not willing to see it buried in the rubble,” the man, Ángel Sánchez Santiago, told the newspaper La Razón. “It was a sign that we residents of Juchitán should not be on our knees in the face of this phenomenon, we have to be strong to get ahead.”

Commenters on social media marveled at Sánchez’s patriotism, in spite of his meagre salary of 2,000 pesos (£85) per month. In contrast, Mexican politicians were widely condemned for trying to take advantage of the earthquake relief effort – such as the government of Veracruz state, which included political propaganda with its assistance bundles.

President Enrique Peña Nieto was expected to return to the affected areas on Monday. Over the weekend, he tweeted “solidarity with the population of Florida” as Hurricane Irma struck, but Mexicans noted that his US counterpart had failed to even mention the earthquake.

Mexico’s offer of assistance with Harvey was made the same day Donald Trump tweeted fresh invective toward Mexico. He threatened, again, to rip up the North American Free Trade Agreement and disparaged Mexico as “one of the highest crime nations in the world”.

The Mexican offer was never accepted by the Trump administration, though some officials such as secretary of state Rex Tillerson and Texas governor thanked Mexico for its generosity.
