Japanese car giant Toyota said on Thursday its first-half net profit edged up from a year earlier, thanks to solid sales and cost-cutting efforts.

The maker of the Camry sedan and Prius hybrid reported net profit rose 2.6 percent to 1.27 trillion yen ($11.7 billion) in April-September.

The company kept its full-year net profit forecast at 2.15 trillion yen and operating profit at 2.4 trillion yen on sales of 29.5 trillion yen, though it made a minor change to its forecast for pretax profit.

Factors including cost reductions and marketing helped outweigh negative impacts from foreign currency exchange rates, contributing to a 11.3 percent rise in operating profit, or 1.40 trillion yen for the six months to September, Toyota said in a statement.

The firm assumed foreign exchange rates at 107 yen to the dollar, compared with 106 yen to the dollar in the previous estimate.

Toyota also announced it would buy up to 34 million of its own stock, or 1.19 percent of its outstanding shares, for up to 200 billion yen by the end of the current business year.

Shares in the firm, which had been trading in negative territory in the morning, were up 0.86 percent soon after the results were released.

"Toyota is enjoying steady global sales although competition is intensifying in the global auto market," Satoru Takada, auto analyst at research and consulting firm TIW, told AFP ahead of the report.

"Demand for hybrid cars -- Toyota's strength -- remains strong as electric cars are still in a transition period," he said.

However, Japan-US trade negotiations "remain a potential threat to Japanese carmakers", he warned, adding that "protectionism appears to likely remain unchanged in the US even if the Democrats win the presidency".

US President Donald Trump's administration has threatened to impose tariffs on Japanese cars imported to the American market.
