As tensions grow between Colombia and Venezuela, the two countries are hosting rival music concerts on their sides of the border. This comes as the Venezuelan opposition has promised that aid will enter Venezuela Saturday, defying the government's orders.

Colombia will host a concert organized by British businessman Richard Branson, headlined by some of the biggest stars in the Spanish language, including Alejandro Sanz, Maluma and Carlos Vives. Organizers estimate some 250,000 people will attend the Venezuela Aid Live concert which aims to raise 100 million U.S. dollars in food and medicine for Venezuela.

The concert also aims to pressure the Venezuelan government into accepting shipments of humanitarian aid donated by the U.S. The aid currently sits in a warehouse on the Colombian border after the government of Venezuela refused its entry into the country. Venezuelan President Nicolas Maduro calls it part of an attempted "coup" to topple his government.

Colombia, the U.S. and some European countries have recognized opposition leader Juan Guaido as the interim president of Venezuela, and have demanded that Maduro step down. American officials have publicly called on Venezuela's military to abandon Maduro. The White House and the Venezuela opposition have floated the idea of a possible military clash with Venezuela, although most analysts consider this unlikely.

Maduro has announced Venezuela's own concert titled "Hands Off Venezuela." The Venezuelan leader said that his government will distribute thousands of boxes of aid to the poor in Colombia, a country with its own poverty and scarcity which has seen thousands of indigenous children die of starvation in recent years.

These concerts are setting the scene for a potential clash Saturday when the Venezuelan opposition says that it will attempt to force the aid into Venezuela. The opposition has said that it wants to form a human chain to cross the aid into Venezuela. They are calling on the border guards and the army to let the aid into the country, which is experiencing an economic collapse that has seen more than three million Venezuelans flee the country.

China's Foreign Ministry said Friday that China opposes any actions causing tension or unrest.
