Ex-steelworker and Neath Port Talbot councillor John Warman has arrived in London where he intends to give a letter to China's ambassador to the UK, Liu Xiaoming, in protest at the "huge amount of cheap steel imports from China".
He said: "I want him to make a direct appeal to his government.
"It's a personal appeal to him, man to man, about the effect it is having on the community. They're almost giving the steel away.
"The steel works are the backbone of the economy in this part of Wales.
"Everybody knows someone who works there or has a connection with the plant. It's the life-blood of the community."

Speaking on a visit to a mosque in Yorkshire, David Cameron said: "This is obviously sad news about the job losses at Port Talbot and elsewhere. We'll work very closely with the company, with the local communities to do everything we can, to get people the training and the assistance they need. And we'll continue to help the steel industry.
"There is obviously this worldwide glut of overproduction of steel that's affecting countries right around the world but the steel industry has asked us for action on energy prices and we've taken that. They've asked us for action on procuring more British steel - we've taken action on that. They want us to take action within the European Union and we've done that as well but we'll continue to work with them.
"I want to have a strong British steel industry at the heart of our important manufacturing base."
Dave Hulse from the GMB union, said: "Once again this is more heartbreaking news for the steel industry and our members. Once again this demonstrates that this government is asleep when it comes to the serious problems that we are facing."

Simon Atkinson from BBC News in Mumbai says steel is one of India's biggest businesses - but has similar problems to those in Wales.
"Tata is India’s biggest conglomerate, involved in everything from cars to hotels, tea to telecoms, salt to airlines.
"Steel though is one of its biggest businesses. A city built around it more than a century ago is now home to about 800,000 people.
"Today Tata Steel has operations in 26 countries. But in nearly all of those markets it is struggling. And the problems it has in Wales – including the falling steel price, sluggish global demand and the influx of cut-price Chinese steel exacerbating oversupply – are also ones it has to grapple with here in India.
"Just last week a ratings agency downgraded Tata Steel’s Indian business – because of its slowing of cash flow and plummeting profit.
"Tata’s management here in Mumbai is in damage limitation mode – and is trying to offload part of its European operations.
"Cutting jobs – making operations cheaper – might just make that a more attractive business to sell."
Tata has confirmed that 15 jobs will be cut at Trostre
