BEIJING - China will take all necessary measures to safeguard its legitimate interests, foreign ministry spokesperson Lin Jian said on Monday, as Washington prepares to impose an additional 10 percent tariff on Chinese goods starting Tuesday.

Lin made the remarks at a regular press briefing when asked about a media report stating that China is formulating countermeasures against the proposed US tariff, with US agricultural and food products likely to be targeted.
