Pascale Harter introduces stories from China, Afghanistan, Chile and Spain.

In Beijing this week, Xi Jinping showed off the Chinese military's newest weaponry - and showcased his nation's growing diplomatic clout too. As he walked with Russia' President Putin and North Korea’s Supreme Leader Kim Jong Un in Tiananmen Square, ÃÛÑ¿´«Ã½ China correspondent Laura Bicker was watching on.

Afghanistan's recent earthquake and aftershocks killed at least 1400 people. As homes, roads and wells crumbled to dust, help was slow to reach affected villages, and international aid isn't likely to arrive quickly - as donor nations are wary of handing money to its Taliban government. Yogita Limaye saw in Jalalabad how the Talibans' strict social rules were applied to female survivors of the disaster.

Copper mining is a mainstay of Chile's economy - and demand for the red metal will only rise as more and more of the world's energy usage goes electric. But getting it out of the ground is often a highly polluting process. Robin Markwell recently visited Chiquicamata, in the Atacama desert - a settlement of 25,000 people which went from boom town to ghost town after it was declared too toxic to live in.

This summer Spain has endured some of its worst wildfires in recent years. Even in Galicia - a region sometimes nicknamed 'the Ireland of Spain' for its heavy rains and green fields - blazes have ripped across the landscape. This part of the country is also home to Europe’s largest surviving herds of wild horses - and it turns out they can help limit the spread of the fires. But for how long? John Murphy went to find out.
